In my game, I need to ensure that angles do not exceed 2 pi. so I use fmod(angle,TWO_PI);
Is this noticeably expensive to do about 100 times per second?

100 times per second? That’s almost zero, you shouldn’t trouble yourself.
Even if fmod takes 100 clock cycles – that’s 10,000 cycles/Sec. For 1 1GHz CPU – that’s 0.001% CPU.
BTW: why do you want to do fmod of TWO_PI? If you’re going to take sin() or cos() – you can skip it.
