- # = Action View Number Helpers
- module Helpers #:nodoc:
-
- # Provides methods for converting numbers into formatted strings.
- # Methods are provided for phone numbers, currency, percentage,
- # precision, positional notation, file size and pretty printing.
- #
- # Most methods expect a +number+ argument, and will return it
- # unchanged if can't be converted into a valid number.
- module NumberHelper
-
- # Raised when argument +number+ param given to the helpers is invalid and
- # the option :raise is set to +true+.
- class InvalidNumberError < StandardError
- attr_accessor :number
- def initialize(number)
- @number = number
- end

-
- # Formats a +number+ into a US phone number (e.g., (555)
- # 123-9876). You can customize the format in the +options+ hash.
- #
- # ==== Options
- #
- # * <tt>:area_code</tt> - Adds parentheses around the area code.
- # * <tt>:delimiter</tt> - Specifies the delimiter to use
- # (defaults to "-").
- # * <tt>:extension</tt> - Specifies an extension to add to the
- # end of the generated number.
- # * <tt>:country_code</tt> - Sets the country code for the phone
- # number.
- # * <tt>:raise</tt> - If true, raises +InvalidNumberError+ when
- # the argument is invalid.
- #
- # ==== Examples

- # one: "meter"
- # other: "meters"
- # thousand:
- # one: "kilometer"
- # other: "kilometers"
- # billion: "gazillion-distance"
- #
- # Then you could do:
- #
- # number_to_human(543934, units: :distance) # => "544 kilometers"
- # number_to_human(54393498, units: :distance) # => "54400 kilometers"
