NumberNameString

Converts between numbers and their cardinal (ex: two) and ordinal (ex: second) names.

Pure Ruby with no dependencies outside of the standard library.

Installation

Add this line to your application's Gemfile:

gem 'number_name_string'

And then execute:

$ bundle

Or install it yourself as:

$ gem install number_name_string

Usage

NumberNameString has a few interfaces, the simplest is using Module methods:

NumberNameString[4032]             # "four hundred thirtytwo"
NumberNameString['six thousand']   # 6000

The Convert class can be instantiated and used directly:

numname = NumberNameString::Convert.new
numname[2000099]                          # "two million ninetynine"
numname['sixtytwo']                       # 62

Or, as a mixin directly on Fixnum and String classes:

include NumberNameString
716.to_cardinal            # "seven hundred sixteen"
716.to_ordinal             # "seven hundred sixteenth"
"four thousand two".to_i   # 4002
91346.to_comma             # "91,346"
'five thousand'.to_comma   # "5,000"
