On modern day Intel cpus (no idea on AMD's side) math using longs is faster than math using floats. ymmv depending on architecture.

Floats were not historically adopted for speed, but because you can get more decimal places with small numbers like 8 bit numbers.

Today with 64 and 128 bit numbers, floating point loses most of its historical benefit, but of course it still has its benefits.
