View Source ExCatalog.Cldr.Rbnf.Ordinal (ex_catalog v1.5.6)

Functions to implement the ordinal rule-based-number-format rules of CLDR.

As CLDR notes, the data is incomplete or non-existent for many languages. It is considered complete for English however.

The standard public API for RBNF is via the Cldr.Number.to_string/2 function.

The functions on this module are defined at compile time based upon the RBNF rules defined in the Unicode CLDR data repository. Available rules are identified by:

iex> ExCatalog.Cldr.Rbnf.Ordinal.rule_sets(:en)

iex> ExCatalog.Cldr.Rbnf.Ordinal.rule_sets("fr")
...> |> Enum.sort()

A rule can then be invoked on an available rule_set. For example

iex> ExCatalog.Cldr.Rbnf.Ordinal.digits_ordinal(123, :en)

This call is equivalent to the call through the public API of:

iex> ExCatalog.Cldr.Number.to_string(123, format: :ordinal)
{:ok, "123rd"}
