This is the changelog for Cldr v2.32.0 released on September 12th, 2023. For older changelogs please consult the release tag on GitHub

Bug Fixes

  • Fixes RBNF rules for fractions. Previous the rule :spellout_cardinal was being used to format the fractional part of a number. However this rule is not defined for many locales. This is changed to :spellout_numbering which is available in all known locales.

Cldr Numbers v2.32.1

This is the changelog for Cldr v2.32.0 released on September 9th, 2023. For older changelogs please consult the release tag on GitHub

Bug Fixes

  • Use currency default fractional digits for currency formats if no :fractional_digits option is provided. Thanks to @dhedlund for the report. This reverts that change made in 2.31.3 which was described as "Don't override currency fractional digits when formatting a number. The format should always define the fractional digits unless overriden by the :fractional_digits option." Fractional digits will also be set to the currency definition of digits unless overriden.

  • Improve several error messages around number systems and RBNF rules.

Deprecations

Enhancements

Cldr Numbers v2.31.3

This is the changelog for Cldr v2.31.3 released on July 24th, 2023. For older changelogs please consult the release tag on GitHub

Bug Fixes

  • Support format: :scientific which is documented but was not implemented as a valid option. Thanks to @petrus-jvrensburg for the report. Closes #38.

  • Don't override currency fractional digits when formatting a number. The format should always define the fractional digits unless overriden by the :fractional_digits option.

Cldr Numbers v2.31.2

This is the changelog for Cldr v2.31.2 released on July 7th, 2023. For older changelogs please consult the release tag on GitHub

Bug Fixes

  • Fixes formatting of numbers in locales where the locale has no RBNF. Thanks to @petrus-jvrensburg for the report. Closes #37.

Cldr Numbers v2.31.1

This is the changelog for Cldr v2.31.1 released on May 17th, 2023. For older changelogs please consult the release tag on GitHub

Bug Fixes

  • Ensure all RBNF rule names are valid function names. In at least one case ("2d_year") a rule name does not map to a valid Elixir function name. The rules are built with atom function names which is valid, but the string versions of that name do not parse. MyApp.Cldr.Rbnf.Spellout.2d_year/2 does not parse, evening though the function exists. This can cause interoperabiity issues with other libraries the introspect code, like inch_ex. From this release, rule names are forced to be valid, parseable function names by prepending an "r" to the rule name if the rule name starts with a digit. Thanks to @ggarciajr for the report.

Cldr Numbers v2.31.0

This is the changelog for Cldr v2.31.0 released on April 28th, 2023. For older changelogs please consult the release tag on GitHub

Enhancements

Cldr Numbers v2.30.1

This is the changelog for Cldr v2.30.1 released on March 28th, 2023. For older changelogs please consult the release tag on GitHub

Bug Fixes

  • Fixes currency formats where the currency symbol is neither the first or last token. Thanks to @simoncocking for the issue. Closes #35.

Cldr Numbers v2.30.0

This is the changelog for Cldr v2.30.0 released on March 7th, 2023. For older changelogs please consult the release tag on GitHub

Bug Fixes

  • Fix short formatting for decimal numbers. Thanks to @dbernheisel for the report. Closes #34.

  • Fix formatting negative numbers when the currency symbol results in an alphabetic character next to the number. In these cases a special format :currency_alpha_next_to_number (or :accounting_alpha_next_to_number) is used. These formats are only available in CLDR42 or later and therefore ex_cldr version 2.35.0 or later is required.

  • Specifies Elixir 1.11 or later in alignment with the requirements for ex_cldr.

Enhancements

  • Supports the :default_currency_format backend configuration option introduced in ex_cldr version 2.35.0.

  • Adds :from_locale as a valid value to the :currency option to Cldr.Number.to_string/3. If set, the currency is derived from the locale.

Cldr_Numbers v2.29.0

This is the changelog for Cldr v2.29.0 released on January 17th, 2023. For older changelogs please consult the release tag on GitHub

Behavior change

  • In prior releases formatting a number as format: :currency would derive the currency code from the locale if no :currency was provided. This is no longer the case. As of CLDR42 a format :currency_no_symbol is defined to allow formatting of the number without an associated symbol. Now when format: :currency is passed without a :currency option, the format is changed to format: :currency_no_symbol. To retain the existing behaviour, pass currency: Cldr.Currency.currency_from_locale(locale) as an option.

  • In prior releases the currency format (:currency or :accounting) would be overriden by any choice expressed in the locale. That is no longer the case from this release. To retain the existing behaviour, pass format: Cldr.Currency.currency_format_from_locale(locale) as an option.

Enhancements

  • Adds an option :wrapper to Cldr.Number.to_string/2. The argument is a 2-arity function that receives the parameters string and tag where tag is one of :number, :currency_symbol, :currency_space, :literal, :quote, :percent, :permille, :minus or :plus. The function must return a string or a "safe string" such as that returned by Phoenix.HTML.Tag.content_tag/3. The function can be used to wrap format elements in HTML or other tags. Thanks to @rubas for the motivation and review. Example:

    iex> Cldr.Number.to_string(100, format: :currency, currency: :USD, wrapper: fn
    ...>   string, :currency_symbol -> "<span class=\"symbol\">" <> string <> "</span>"
    ...>   string, :number -> "<span class=\"number\">" <> string <> "</span>"
    ...>   string, :currency_space -> "<span>" <> string <> "</span>"
    ...>   string, _other -> string
    ...> end)
    {:ok, "<span class=\"symbol\">$</span><span class=\"number\">100.00</span>"}
    
    # It is also possible and recommended to use the `Phoenix.HTML.Tag.content_tag/3`
    # function if wrapping HTML tags since these will ensure HTML entities are
    # correctly encoded.  For example:
    iex> Cldr.Number.to_string(100, format: :currency, currency: :USD, wrapper: fn
    ...>   string, :currency_symbol -> Phoenix.HTML.Tag.content_tag(:span, string, class: "symbol")
    ...>   string, :number -> Phoenix.HTML.Tag.content_tag(:span, string, class: "number")
    ...>   string, :currency_space -> Phoenix.HTML.Tag.content_tag(:span, string)
    ...>   string, _other -> string
    ...> end)
    {:ok, "<span class=\"symbol\">$</span><span class=\"number\">100.00</span>"}
  • Adds the number formats :currency_no_symbol and :accounting_no_symbol that can be used to format currency amounts without an associated currency symbol.

  • Removes the Cldr.Number.to_string/3 requirement for a currency to be provided (or derived) when the format is :currency. If a currency is provided, the format :currency is used. If a currency is not provided, the format :currency_no_symbol is used.

Cldr_Numbers v2.28.0

This is the changelog for Cldr v2.28.0 released on October 24th, 2022. For older changelogs please consult the release tag on GitHub

Enhancements

  • Encapsulates CLDR 42 data. Unless otherwise noted, all the changes are reflected in ex_cldr libraries and functions.

Cldr_Numbers v2.27.3

This is the changelog for Cldr v2.27.3 released on October 8th, 2022. For older changelogs please consult the release tag on GitHub

Bug Fixes

  • Cldr.Number.to_string/3 with format: :narrow and :currency set will use the currency's narrow symbol.

  • Apply currency spacing for short formats (previously not being applied)

Cldr_Numbers v2.27.2

This is the changelog for Cldr v2.27.2 released on July 21st, 2022. For older changelogs please consult the release tag on GitHub

Bug Fixes

  • Fix :short formatting of decimal numbers with specified fractional digits. Thanks to @glennr for the report. Closes #32.

Cldr_Numbers v2.27.1

This is the changelog for Cldr v2.27.1 released on July 20th, 2022. For older changelogs please consult the release tag on GitHub

Bug Fixes

  • Fix :short formatting of negative numbers. Thanks to @glennr for the report. Closes #30.

Cldr_Numbers v2.27.0

This is the changelog for Cldr v2.27.0 released on May 14th, 2022. For older changelogs please consult the release tag on GitHub

Enhancements

  • Add support for formatting numbers representing ISO 24165 Digital Tokens (aka crypto currencies). The behaviour follows that for currency formatting. Given that the digital token registry does not contain fraction precision data or pluralised or localised token names, the formatting of digital tokens amounts is not localized beyond formatting the number itself.

Cldr_Numbers v2.26.0

This is the changelog for Cldr v2.26.0 released on April 6th, 2022. For older changelogs please consult the release tag on GitHub

Enhancements

Cldr_Numbers v2.25.2

This is the changelog for Cldr v2.25.1 released on March 2nd, 2022. For older changelogs please consult the release tag on GitHub

Bug Fixes

  • Fixes formatting of Decimal Inf and NaN numbers. Thanks to @sh41 for the report. Closes #26.

Cldr_Numbers v2.25.1

This is the changelog for Cldr v2.25.1 released on February 22nd, 2022. For older changelogs please consult the release tag on GitHub

Bug Fixes

  • Remove compiler warnings on Elixir 1.11. Thanks to @koszta for the report. Fixes #24.

  • Remove spurious @dialyzer directives that are no longer required (because we understand dialyzer a little bit more now).

Cldr_Numbers v2.25.0

This is the changelog for Cldr v2.25.0 released on February 21st, 2022. For older changelogs please consult the release tag on GitHub

Enhancements

  • Updates to ex_cldr version 2.26.0 which uses atoms for locale names and rbnf locale names. This is consistent with out elements of t:Cldr.LanguageTag where atoms are used where the cardinality of the data is fixed and relatively small and strings where the data is free format.

Cldr_Numbers v2.24.0

This is the changelog for Cldr v2.24.0 released on December 30th, 2021. For older changelogs please consult the release tag on GitHub

Enhancements

  • Allowed limited forms of format composition. For example, composing a :long format with a :currency format:

    iex> Cldr.Number.to_string!(100_000_000, format: :long) |> Cldr.Number.to_string(format: :currency)
    {:ok, "$100 million"}
  • Add format :currency_long_with_symbol which is a composite of :currency_long and the locales standard currency format. This supports formatting of of numbers like "$100 million" in the example above.

Cldr_Numbers v2.23.3

This is the changelog for Cldr v2.23.3 released on December 14th, 2021. For older changelogs please consult the release tag on GitHub

Cldr_Numbers v2.23.0

This is the changelog for Cldr v2.23.0 released on October 27th, 2021. For older changelogs please consult the release tag on GitHub

Enhancements

Bug Fixes

  • Arbitrary RBNF rule lookup falls back to the root locale (called "und") when checking if a rule is available. Thanks to @maennchen for the report. Closes #22.

  • Fixes performance issue when calling Cldr.Number.to_string/3 with an arbitrary RBNF rule name. Previously these formats would mistakenly read the raw json file for a locale incurring a significant performance penaly. Performance is now 100x faster as expected. Thanks to @maennchen for the bug report. Closes #21.

Cldr_Numbers v2.20.0

This is the changelog for Cldr v2.20.0 released on August 17th, 2021. For older changelogs please consult the release tag on GitHub

Bug Fixes

  • Improve number parsing with Cldr.Number.Parser.scan/2 when the string has lists of numbers separated by commas. Thanks to @DaTrader for the report. Closes #19.

Enhancements

  • Add support for custom currency symbols. This extends the use of the :currency_symbol option. In previously releases this option was required to be :standard or :iso. Now the value can also be :narrow, :symbol or a string which will be used as the currency symbol. From the documentation for Cldr.Number.to_string/3:
    • currency_symbol: Allows overriding a currency symbol. The alternatives are:
      • :iso the ISO currency code will be used instead of the default currency symbol.
      • :narrow uses the narrow symbol defined for the locale. The same narrow symbol can be defined for more than one currency and therefore this should be used with care. If no narrow symbol is defined, the standard symbol is used.
      • :symbol uses the standard symbol defined in CLDR. A symbol is unique for each currency and can be safely used.
      • "string" uses string as the currency symbol
      • :standard (the default and recommended) uses the CLDR-defined symbol based upon the currency format for the locale.

Cldr_Numbers v2.19.0

This is the changelog for Cldr v2.19.0 released on July 1st, 2021. For older changelogs please consult the release tag on GitHub

Enhancements

  • Updated to ex_cldr version 2.23.0 which changes the names of some of the field in the "-u-" extension to match the CLDR canonical name. In particular the field name number_system changes to numbers.

Bug Fixes

Cldr_Numbers v2.18.3

This is the changelog for Cldr v2.18.3 released on June 12th, 2021. For older changelogs please consult the release tag on GitHub

Breaking Change

  • There is a minor breaking change in the error return from Cldr.Number.Parser.parse/2. Previously the error return was {:error, string}. It is now more consistent with the rest of ex_cldr and returns {:error, {exception, message}}

Bug Fixes

  • Fix Cldr.Number.Parser.parse/2 for numbers that are in non-latin scripts (like Thai, Arabic, ...). There are 66 known number systems that have decimal digits as of CLDR39.

Cldr_Numbers v2.18.2

  • Fixes RBNF formatting options setting for :spellout_ordinal

  • Allows any defined RNBF rule for a locale to be invoked as the :format option to Cldr.Number.to_string/3.

Cldr_Numbers v2.18.0

This is the changelog for Cldr v2.18.0 released on May 8th, 2021. For older changelogs please consult the release tag on GitHub

Bug Fixes

  • Fixes short and long number formatting.

  • Fixes formatting whent the format string consists only of digits. Previously this would erroneously set both the maximum and minimum integer digits. Now it only sets the minimum integer digits.

  • Fix bug in Cldr.Number.System.number_system_from/1 to correctly allow a binary language tag without a backend parameter (which will then default to Cldr.default_backend!/0)

Cldr_Numbers v2.16.0

This is the changelog for Cldr v2.16.0 released on November 1st, 2020. For older changelogs please consult the release tag on GitHub

Cldr_Numbers v2.15.1

This is the changelog for Cldr v2.15.1 released on June 23rd, 2020. For older changelogs please consult the release tag on GitHub

Bug Fixes

  • Fixes two number parsing bugs:

    1. A bug whereby decimal and separator symbols would be impacted in non-number strings when using MyApp.Cldr.Number.scan/2
    2. A bug whereby numbers using various localised symbols would not be recognised
  • Fix formatter pipeline generation which was including the round nearest pipeline stage even when not required. Thanks to @jeroenvisser101 for the collaboration. Fixes #14.

Cldr_Numbers v2.13.0

This is the changelog for Cldr v2.13.0 released on May 2nd, 2020. For older changelogs please consult the release tag on GitHub

Breaking change

  • In previous releases, requesting a currency format in Number.to_string/3 without specifying an option :currency would return an error. In this release, a currency is derived from the locale (either the :locale parameter or from backend.get_locale()). The affected currency formats are :currency, :accounting, :currency_long and :currency_short

Enhancements

  • Cldr.Number.to_string/2 now detects the number system from any supplied locale. If provided, the option :number_system takes precedence over the number system derived from a locale.

  • Add :round_nearest formatting option for Cldr.Number.to_string/3. If provided, this option overrides the value defined by the :format option.

  • Refines number system detection. The order of precedence is:

    • The :number_system option if provided

    • The :number_system from the locale if provided

    • The :number_system from the current locale for the supplied backend. This locale is retrieved with backend.get_locale()

Cldr_Numbers v2.12.1

This is the changelog for Cldr v2.12.1 released on March 2nd, 2020. For older changelogs please consult the release tag on GitHub

Bug Fixes

  • Use the RBNF format spellout_numbering instead of spellout_cardinal for the Cldr.Number.to_string/3 option format: :spellout since spellout_numbering has a larger locale coverage of RBNF formats.

Cldr_Numbers v2.12.0

This is the changelog for Cldr v2.12.0 released on January 21st, 2020. For older changelogs please consult the release tag on GitHub

Enhancements

  • Updates version requirement for cldr_utils in order to support versions of decimal from 1.6 up to 2.0.

Bug fixes

  • Fixes an incorrect typespec on Cldr.Number.Format.format_from_locale_or_options/1 that was causing a dialyzer warning

Cldr_Numbers v2.11.0

This is the changelog for Cldr v2.11.0 released on January 19th, 2020. For older changelogs please consult the release tag on GitHub

Enhancements

  • Uses the number system defined by the locale if it is specified. The number system is defined as part of the U extension. The order of precedence is:
    • :default if no option is provided to MyApp.Cldr.Number.to_string/2 and no number system is defined in the locale

    • The option :number_system if it is provided to MyApp.Cldr.Number.to_string/2

    • The locale's number_system if it is defined and the option :number_system to MyApp.Cldr.Number.to_string/2 is not provided

Examples:

 # Locale defines a number system and no option :number_system is provided
 iex> TestBackend.Cldr.Number.to_string(1234, locale: "th-u-nu-thai")
 {:ok, "๑,๒๓๔"}

 # Locale defines a number system but an option :number_system is also provided which
 # take precedence
 iex> MyApp.Cldr.Number.to_string 1234, locale: "th-u-nu-latn", number_system: :thai
 {:ok, "๑,๒๓๔"}

 # A number system is defined in the locale but it is not supported by the
 # locale
 iex> MyApp.Cldr.Number.to_string 1234, locale: "en-AU-u-nu-thai"
 {:error,
  {Cldr.UnknownNumberSystemError,
   "The number system :thai is unknown for the locale named \"en\". Valid number systems are %{default: :latn, native: :latn}"}}
  • Uses the currency code defined by the locale if it is specified and the number format requested is :currency. The currency code is defined as part of the U extension. The order of precedence is:
    • The option :currency if it is provided to MyApp.Cldr.Number.to_string/2

    • The locale's currency code if it is defined and the option :currency to MyApp.Cldr.Number.to_string/2 is not provided

Examples:

 # Use the currency code :AUD specified in the locale
 iex> MyApp.Cldr.Number.to_string 1234, locale: "en-AU-u-cu-aud", format: :currency
 {:ok, "A$1,234.00"}

 # Use the currency code :USD provided as an option in precedence over the currency code
 # defined by the locale
 iex> MyApp.Cldr.Number.to_string 1234, locale: "en-AU-u-cu-aud", format: :currency, currency: :USD
 {:ok, "$1,234.00"}
  • Uses the currency format defined by the locale if it is specified and the number format requested is :currency or :accounting. The currency format is defined as part of the U extension. The order of precedence is:
    • The locale's currency format if it is defined and the option :format to MyApp.Cldr.Number.to_string/2 is either :currency or :accounting. Therefore the locales currency format takes precedence over the :format argument but only if :format is a currency format.

    • The option :format in every other case

Examples:

 # Using in the locale currency format - just happens to be the same as the format option
 iex> MyApp.Cldr.Number.to_string -1234, locale: "en-AU-u-cu-aud-cf-standard", format: :currency
 {:ok, "A$-1,234.00"}

 # The locale format takes precedence over the format option
 iex> MyApp.Cldr.Number.to_string -1234, locale: "en-AU-u-cu-aud-cf-standard", format: :accounting
 {:ok, "A$-1,234.00"}

 iex> MyApp.Cldr.Number.to_string -1234, locale: "en-AU-u-cu-aud-cf-account", format: :accounting
 {:ok, "(A$1,234.00)"}

 iex> MyApp.Cldr.Number.to_string -1234, locale: "en-AU-u-cu-aud-cf-account", format: :currency
 {:ok, "(A$1,234.00)"}

Cldr_Numbers v2.10.0

This is the changelog for Cldr v2.10.0 released on January 15th, 2020. For older changelogs please consult the release tag on GitHub

Bug Fixes

  • Fixes formatting of negative percentages. Actually fixes an issue where the default negative format would be incorrect in many cases. Thanks to @maennchen. Closes #11.

Enhancements

  • Optionally logs a warning if compiling a number format at runtime. The warning is emitted only once for each format to reduce log clutter. The log warning is emitted if the backend configuration key :supress_warnings is set to false (this is the default value). The warn_once mechanism depends on the availability of the :persistent_term module which is only available from OTP 21.2 onwards. On earlier releases of OTP no warning will be emitted.

Cldr_Numbers v2.9.0

This is the changelog for Cldr v2.9.0 released on October 20th, 2019. For older changelogs please consult the release tag on GitHub

Enhancements

  • Adds option :currency_symbol to Cldr.Number.to_string/2. This option, when set to :iso changes a currency format to force using the ISO currency code instead of the native currency symbol.

Cldr_Numbers v2.8.0

This is the changelog for Cldr v2.8.0 released on October 10th, 2019. For older changelogs please consult the release tag on GitHub

Enhancements

  • Update ex_cldr to version 2.11.0 which encapsulates CLDR version 36.0.0 data.

Cldr_Numbers v2.7.2

This is the changelog for Cldr v2.7.2 released on September 7th, 2019. For older changelogs please consult the release tag on GitHub

Bug Fixes

Cldr_Numbers v2.7.1

This is the changelog for Cldr v2.7.1 released on August 23rd, 2019. For older changelogs please consult the release tag on GitHub

Bug Fixes

Cldr_Numbers v2.7.0

This is the changelog for Cldr v2.7.0 released on August 21st, 2019. For older changelogs please consult the release tag on GitHub

Enhancements

  • An option :backend can be passed to Cldr.Number.to_string/3 and it will be used if being called as Cldr.Number.to_string/2. This means that for a call like Cldr.Number.to_string(number, backend, options) which has an option :backend, the call can be replaced with Cldr.Number.to_string(number, options).

Cldr_Numbers v2.6.4

This is the changelog for Cldr v2.6.4 released on June 16th, 2019. For older changelogs please consult the release tag on GitHub

Bug Fixes

Cldr_Numbers v2.6.3

This is the changelog for Cldr v2.6.3 released on June 15th, 2019. For older changelogs please consult the release tag on GitHub

Bug Fixes

  • Correctly interpret the special short format 0 to mean "format as a normal decimal or currency number". Thanks to @epilgrim. Closes #10

Cldr_Numbers v2.6.2

This is the changelog for Cldr v2.6.2 released on June 12th, 2019. For older changelogs please consult the release tag on GitHub

Bug Fixes

Cldr_Numbers v2.6.1

This is the changelog for Cldr v2.6.1 released on June 2nd, 2019. For older changelogs please consult the release tag on GitHub

Bug Fixes

  • Ensure Cldr.Number.to_string/3 doesn't transliterate is the number systems are compatible for a given locale. Basically, if the local and number system don't require transliteration from 0..9 to another script (like indian, arabic, ...) then we don't do it. This improves performance by about 10% for this common case.

Cldr_Numbers v2.6.0

This is the changelog for Cldr v2.6.0 released on March 28th, 2019. For older changelogs please consult the release tag on GitHub

Enhancements

Cldr_Numbers v2.5.0

This is the changelog for Cldr v2.5.0 released on March 23rd, 2019. For older changelogs please consult the release tag on GitHub

Enhancements

  • Supports Cldr.default_backend() as a default for a backend on functions in Cldr.Number

Cldr_Numbers v2.4.4

This is the changelog for Cldr v2.4.4 released on March 21st, 2019. For older changelogs please consult the release tag on GitHub

Bug Fixes

  • Rbnf.Ordinal and Rbnf.Spellout now respect the optional generation of @moduledocs in a backend

Cldr_Numbers v2.4.3

This is the changelog for Cldr v2.4.3 released on March 20th, 2019. For older changelogs please consult the release tag on GitHub

Bug Fixes

  • Fix dialyzer warnings

Cldr_Numbers v2.4.2

This is the changelog for Cldr v2.4.2 released on March 15th, 2019. For older changelogs please consult the release tag on GitHub

Enhancements

  • Makes generation of documentation for backend modules optional. This is implemented by the :generate_docs option to the backend configuration. The default is true. For example:
defmodule MyApp.Cldr do
  use Cldr,
    default_locale: "en-001",
    locales: ["en", "ja"],
    gettext: MyApp.Gettext,
    generate_docs: false
end

Cldr_Numbers v2.4.1

This is the changelog for Cldr v2.4.1 released on March 7th, 2019. For older changelogs please consult the release tag on GitHub

Bug Fixes

  • Fix fractional grouping. Previously when there was no grouping, the group size was being set to the number of fractional digits.

  • Fix scientific precision. Previously the mantissa was not being rounded because the prioritisation of significant digits over exponent digits was not being correctly reconciled.

  • Fix formatting precision of an exponent. A format of 0E00 will now format the exponent with two digits.

  • Fix o silence dialyzer warnings

Cldr_Numbers v2.4.0

This is the changelog for Cldr v2.4.0 released on March 4th, 2019. For older changelogs please consult the release tag on GitHub

Enhancements

Cldr_Numbers v2.3.0

This is the changelog for Cldr v2.3.0 released on March 1st, 2019. For older changelogs please consult the release tag on GitHub

Enhancements

  • Opens up the formatting pipeline for use by other formatting systems like printf. This is implemented by the introduction of Cldr.Number.Format.Meta to create the abstract metadata struct. This struct is used for Cldr.Number.to_string/3 and is now available for use by other libraries. The function Cldr.Number.Formatter.Decimal.to_string/3 is the primary function that should be used by other libraries.

Cldr_Numbers v2.2.0

This is the changelog for Cldr v2.2.0 released on Febriuary 24th, 2019. For older changelogs please consult the release tag on GitHub

Bug Fixes

  • Fix generating an error tuple when the number system is a binary

  • Fix @doc errors

Enhancements

Cldr_Numbers v2.1.1

This is the changelog for Cldr v2.1.1 released on February 3rd, 2019. For older changelogs please consult the release tag on GitHub

Bug Fixes

  • Formats Decimal.new("-0") the same as Decimal.new("0") which is to say without the sign. Although the Decimal standard upon which the Decimal library is based allows for -0, formatting this as a string with the sign is not consistent with the output for integers and floats. Consistency is, in this case, considered to be the correct approach.

  • Fix documentation errors

Cldr_Numbers v2.1.0

This is the changelog for Cldr v2.1.0 released on December 1st, 2018. For older changelogs please consult the release tag on GitHub

Enhancements

iex> MyApp.Cldr.Number.to_at_least_string 1234
{:ok, "1,234+"}

iex> MyApp.Cldr.Number.to_at_most_string 1234
{:ok, "≤1,234"}

iex> MyApp.Cldr.Number.to_approx_string 1234
{:ok, "~1,234"}

iex> MyApp.Cldr.Number.to_range_string 1234..5678
{:ok, "1,234–5,678"}
  • Refactored options for Cldr.Numbers.to_string/3 and other functions that use the common number formatting options structure. Options are now parsed and contained in a Cldr.Number.Format.Options struct. A user-visible benefit is that if passing a Cldr.Number.Format.Options struct to Cldr.Number.to_string/3 then no further validation or normalization will be performed. Therefore if you are formatting in a tight loop and using common options, saving the options in advance will yield some performance improvement. A Cldr.Number.Format.Options struct can be returned by called Cldr.Number.Format.Options.validate_options(backend, options).

Cldr_Numbers v2.0.0

This is the changelog for Cldr v2.0.0 released on November 22nd, 2018. For older changelogs please consult the release tag on GitHub

Breaking Changes

  • ex_cldr_numbers now depends upon ex_cldr version 2.0. As a result it is a requirement that at least one backend module be configured as described in the ex_cldr readme.

  • The public API is now based upon functions defined on a backend module. Therefore calls to functions such as Cldr.Number.to_string/2 should be replaced with calls to MyApp.Cldr.Number.to_string/2 (assuming your configured backend module is called MyApp.Cldr).

Enhancements

  • Adds Cldr.Number.validate_number_system/3 and <backend>.Number.validate_number_system/2 that are now the canonical way to validate and return a number system from either a number system binary or atom, or from a number system name.

  • Cldr.Number.{Ordinal, Cardinal}.pluralize/3 now support ranges, not just numbers

  • Currency spacing is now applied for currency formatting. Depending on the locale, some text may be placed between the current symbol and the number. This enhanced readability, it does not change the number formatting itself. For example you can see below that for the locale "en", when the currency symbol is text, a non-breaking space is introduced between it and the number.

iex> MyApp.Cldr.Number.to_string 2345, currency: :USD, format: "¤#,##0.00"
{:ok, "$2,345.00"}

iex> MyApp.Cldr.Number.to_string 2345, currency: :USD, format: "¤¤#,##0.00"
{:ok, "USD 2,345.00"}
