Converting numbers

Hey
I've made a scroller that fits to the inside of a box.
This means that the distance from the top and bottom of the scrollbar is different whenever you resize the box.

Lets say at the moment when I scroll the drag bar's y coordinate moves from 12 to 120

This is fine, but I would like a seperate script that will convert this into out of a hundred. (1-100).

Any help would be great,

code:

---

function getPos(min:Number, pos:Number, max:Number) {

	var _tracklength:Number = max-min;

	var _trackpos:Number = pos-min;

	return _trackpos/_tracklength;

}

function getPCPos(min:Number, pos:Number, max:Number) {

	return Math.round(100*getPos(min, pos, max));

}

trace(getPos(12, 56, 120)+" is roughly "+getPCPos(12, 56, 120)+" %");

---

Thank you AGC :)

I have edited it to suit my needs and it works perfectly,

Many thanks! :D
