Without being able to understand all that code, I suspect that your
use of  fractions results in all remainders being done on integral
arguments, and the standard fmod() works quite well there.
I have only seen fmod()'s bad behavior occur with real, non-integral
arguments that are multiples of one another (like: remainder (3.9, 1.3))
A really nice work-around!! (though I'm sure a fractions package has other
reasons to exist)
