// Not enough context here to be useful, I will make a self-contained example soon.

// This code allocates memory:
_timer += (FP.timeInFrames ? _anim._frameRate : _anim._frameRate * FP.elapsed) * rate;

// This code does not:
var timeAdd:Number = _anim._frameRate * rate;
if (! FP.timeInFrames) timeAdd *= FP.elapsed;
_timer += timeAdd;

// Types:
_timer: Number
FP.timeInFrames: Boolean
_anim: Anim (contains _frameRate: Number)
FP.elapsed: Number
rate: Number
