Help with simplifying code

[Adamkyler]

Hello, I have made a AS 2.0 script that allows an object to ease into rotation. Here is the code:

_root.onEnterFrame = function(){
	rot = Math.atan2(_ymouse-arrow._y,_xmouse-arrow._x)*180/Math.PI;
	if(arrow._rotation-rot>180){
		rot += 360
	}
	if(arrow._rotation-rot<-180){
		rot -= 360
	}
	arrow._rotation += (rot-arrow._rotation)/3;
}

Is this the best way to write it, or is there something more simple that I can do?

Go to tweenmax.com - download tweenmax for as2.

Much simpler, many options, easy to use.

Thats not really what I am looking for. I have created my own program that makes arrays of rotations. I then copy those arrays into my game, and I can reference to them and dynamically combine them into poses and animations for my characters. All I need to know is if there is a better way to write my easing code.
