This gem lets you emulate 2's complement integers in ruby.

Add this line to your application's Gemfile:

gem 'bitint'

And then execute:

$ bundle install

Or install it yourself as:

$ gem install bitint

num = BitInt::U8.new(0xFE)
num += 2
puts num #=> 1

After checking out the repo, run bin/setup to install dependencies. Then, run rake test to run the tests. You can also run bin/console for an interactive prompt that will allow you to experiment.

To install this gem onto your local machine, run bundle exec rake install. To release a new version, update the version number in version.rb, and then run bundle exec rake release, which will create a git tag for the version, push git commits and the created tag, and push the .gem file to rubygems.org.
