move_f32_towards()

void move_f32_towards	(	f32 *	startingValue,
		f32	targetValue,

	)

Function: move_f32_towards

Parameters: f32 *startingValue - Pointer to the float that will be modified f32 targetValue - Float value to move startingValue towards f32 somePercent - The percent of the difference between startingValue and targetValue to actually move

Moves a given startingValue the given somePercent towards the targetValue

f32 *thing = 2500; move_f32_towards(thing, 500, 0.75f); thing now has a value of 1000

If after the move startingValue is inside of the range [-0.001, 0.001], force it to exactly 0.0f

This is probably a precision thing. The scaling with somePercent likely can't hit exactly 0 with any reliability, so they force it to 0 if you're in a small range around it. Why they only do this for 0 is anyone's guess though
