FriendlyNumbers (aka Friendly)

Friendly number helpers without the mess. Working on a Roda or Sinatra application and want to format a number into a currency or friendly file size? Got you covered.

Rails-like helpers for number_to_currency and number_to_human_size

Installation

Add this line to your application's Gemfile:

gem 'friendly_numbers'

And then execute:

$ bundle

Or install it yourself as:

$ gem install friendly_numbers

Usage

To format a value as a currency:

FriendlyNumbers.number_to_currency 123.45  # => "$123.45"

To format a value as a human file size:

FriendlyNumbers.number_to_human_size 12345.67  # => "12.056 KB"

To format time in seconds to an elapsed time:

FriendlyNumbers.seconds_to_time(65) # => "1m 5s"

Also conveniently aliased under the Friendly namespace.

Gem breaks on large negatives

See below. I think the tests should cover much larger values. Thanks!

Looks like this will do the trick (whole being the variable you're using):
whole.to_s.reverse.gsub(/...(?!-)(?=.)/,'\&,').reverse
