% (mod) for floats

[beakie]

Need some code to perform a mod style algorithm on floats or doubles.

So... 123.2 % 3 = 0.2

Any ideas?

// goal:   result = orig % mod
result = orig - ( (int)(orig / mod) * mod );

Funky. Nice one.

You can use std::fmod

oh yeah.. duh. I always forget fmod exists because I confuse it for modf.
