Math.pow()

Availability
Flash Player 5. In Flash Player 4, the methods and properties of the Math class are emulated using
approximations and might not be as accurate as the non-emulated math functions that Flash
Player 5 supports.
Usage
Math.pow(x:Number , y:Number) : Number
Parameters
A number to be raised to a power.
x
A number specifying a power the parameter
y
Returns
A number.
Description
Method; computes and returns
Example
The following example uses
this.createEmptyMovieClip("canvas_mc", this.getNextHighestDepth());
var mouseListener:Object = new Object();
mouseListener.onMouseDown = function() {
this.origX = _xmouse;
this.origY = _ymouse;
};
mouseListener.onMouseUp = function() {
this.newX = _xmouse;
this.newY = _ymouse;
var minY = Math.min(this.origY, this.newY);
var nextDepth:Number = canvas_mc.getNextHighestDepth();
var line_mc:MovieClip =
canvas_mc.createEmptyMovieClip("line"+nextDepth+"_mc", nextDepth);
line_mc.moveTo(this.origX, this.origY);
line_mc.lineStyle(2, 0x000000, 100);
line_mc.lineTo(this.newX, this.newY);
var hypLen:Number = Math.sqrt(Math.pow(line_mc._width,
2)+Math.pow(line_mc._height, 2));
line_mc.createTextField("length"+nextDepth+"_txt",
canvas_mc.getNextHighestDepth(), this.origX, this.origY-22, 100, 22);
line_mc['length'+nextDepth+'_txt'].text = Math.round(hypLen) +" pixels";
};
Mouse.addListener(mouseListener);
