* ruby -v: ruby 2.1.5p273 (2014-11-13 revision 48405) [x86_64-linux]
* Backport: 2.0.0: UNKNOWN, 2.1: UNKNOWN
----------------------------------------
1.1+1.1+1.1 = 3.3

However in the current 2.1.5 this is what happens:

dmolnar@domalaptop:~> irb
2.1.5 :001 > 1.1+1.1+1.1
 => 3.3000000000000003 
2.1.5 :002 >
