Ruby Change Maker

Given a currency amount (assuming US Currency ) expressed as a floating point number ( i.e. 1.25 or 0.75 ) returns that amount expressed as the least amount of change using the least number of bills, coins, or combination of bills and coins.

To use as a gem:

gem install RubyChangeMaker

Then, in your source file:

require 'RubyChangeMaker'

cm = RubyChangeMaker::Change.new
amt = 1.25 # for $1.25, use 0.75 for .75 cents, etc.
dollars, cents = cm.make_change(amt)

To see an example program using the Module, look in this repo’s bin/ directory

To work with the source files:

To Run:

cd into bin/ and type: './changemaker' (the file is already chmod'd)

To Run Tests:

(require's cucumber)
cd into root directory ( 'ruby-change-maker/' ), then type: cucumber

NOTES:

• Source is in lib/rubychangemaker/.
• lib/rubychangemaker.rb is just some boot-strapping for cucumber.
• features/support/ again, boot-strapping for cucumber.
