Because the code calculates in rationals?

You might want to 'require "mathn"' on the beginning of the script if it  
bugs you, the module causes Ruby math to work more... err...  
mathemathically. E.g.:

irb(main):001:0> Rational(2, 1)
=> Rational(2, 1)
irb(main):002:0> require "mathn"
=> true
irb(main):003:0> Rational(2, 1)
=> 2

As always after doing deeper magic, be on the lookout for bugs the module  
could introduce.
