atan2() Function

A function I didn't realize was missing until I found out how amazingly awesome it is is atan2(). Any chance it could be added for the next build?

I wrote atan2 as a formula in an event, only to later realize there is an angle compare expression that does the same job I wanted done.

AngleDiff(a, b)

Is that what you're trying to do? measure of the arc between two angles?

The angle() expression which measures the angle between two points uses atan2. I'm not aware of any other uses for atan2.

If you pass 0 as one of the two positions the result is exactly equal to atan2, ie. angle(0, 0, x,y) is equal to atan2(y, x).

I didn't even think of doing that with the angle() expression. I'm using the function to get the angular speed of an object based on it's separate X and Y speeds.
