defmodule Number do
  @moduledoc """
  `Number` provides functions to convert numbers into a variety of different
  formats. Ultimately, it aims to be a partial clone of
  [ActionView::Helpers::NumberHelper](http://api.rubyonrails.org/classes/ActionView/Helpers/NumberHelper.html)
  from Rails.

  If you want to import all of the functions provided by `Number`, simply `use`
  it in your module:

      defmodule MyModule do
        use Number
      end

  More likely, you'll want to import the functions you want from one of
  `Number`'s submodules.

      defmodule MyModule do
        import Number.Currency
      end

  ## Configuration

  Some of `Number`'s behavior can be configured through Mix. Each submodule
  contains documentation on how to configure it.
