libeuler is a simple library you can include in your code to take away some of the boring repetitive parts of solving Project Euler problems.
Adds various methods to the Integer class, such as factorial, prime?, is_fibonacci?, etc.
Provides various module methods, such as generate_sieve, get_primes, etc.
require 'rubygems' require 'euler' 5.factorial # => 120
sudo gem install euler
Fork the project.
Make your feature addition or bug fix.
Add tests for it. This is important so I don't break it in a future version unintentionally.
Commit, do not mess with rakefile, version, or history. (if you want to have your own version, that is fine but bump version in a commit by itself I can ignore when I pull)
Send me a pull request. Bonus points for topic branches.
