View Source Better Number

BetterNumber is an Elixir library which provides functions to convert numbers into a variety of different formats. It is a fork of Daniel Berkompas's Number but it

  1. Has slightly more features

  2. Does not perform any configuration lookups and therefore each function is 100% pure.

  3. Has no __using__ to import functions

  4. Has correct type specifications

  5. Actively maintained

Features

  • Conversion to currency, where everything is customizable
BetterNumber.to_currency(2034.46)
"$2,034.46"
  • Conversion to international phone format
BetterNumber.to_phone(1112223333, area_code: true, country_code: 1)
"+1 (111) 222-3333"
  • Conversion to percentage
BetterNumber.to_percentage(100, precision: 0)
"100%"
  • Conversion to human readable format
BetterNumber.to_human(1234)
"1.23 Thousand"
  • Just splitting the number with commas
BetterNumber.to_delimited(12345678)
"12,345,678"

Note:

Every function is extremely customizable, and has a ton of options
