sqrt (Math.sqrt method)

public static sqrt(x:Number) : Number
Computes and returns the square root of the specified number.
Availability: ActionScript 1.0; 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.
Parameters
- A number or expression greater than or equal to 0.
x:Number
Returns
- A number if parameter x is greater than or equal to zero; NaN (not a number)
Number
otherwise.
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;
