Oops, I didn't realize that Ruby comes with an Epsilon. This should be a 
fine test for equality:

return (num1-num2).abs < Float::EPSILON

Now, whether Float#==(other) should make this check might be worth 
thinking about, but I really have no opinion on the matter--I'm used to 
not comparing floats like this.
