An int value can be more precise then a float can, however a float can
hold bigger numbers. It's the difference between having a 24 bit
fraction with 8 bits of exponent and 1 of sign vs 31/32 bits of
fraction data without exponent. Plus, integer operations are faster
then floating point operations, even if just margionably.
