The standard library docs don't make sense to me a lot of the time.
How do I use the gcd2 method in class Integer (or is it in file
mathn.rb . . . no idea)?

Here's a link to what I'm looking at:

Are you using 1.8.x or 1.9.x? The method is defined in mathn.rb for 1.8
but not for 1.9.

Both, sort of.

ruby 1.8.7 (2008-08-11 patchlevel 72) [i686-linux]

irb(main):001:0> require 'mathn'
=> true
irb(main):002:0> 12.gcd(4)
=> 4
