MACROMEDIA FLASH 8-ACTIONSCRIPT 2.0 LANGUAGE - PI (Math.pi Property)

Math 755
Returns
Number - A number.
Example
The following example displays
Sat Dec 25 00:00:00 GMT-0700 2004, which is the smaller
of the evaluated expressions.
var date1:Date = new Date(2004, 11, 25);
var date2:Date = new Date(2004, 11, 30);
var minDate:Number = Math.min(date1.getTime(), date2.getTime());
trace(new Date(minDate).toString());

Example
The following example draws a circle using the mathematical constant pi and the Drawing
API.
drawCircle(this, 100, 100, 50);
//
function drawCircle(mc:MovieClip, x:Number, y:Number, r:Number):Void {
mc.lineStyle(2, 0xFF0000, 100);
mc.moveTo(x+r, y);
mc.curveTo(r+x, Math.tan(Math.PI/8)*r+y, Math.sin(Math.PI/4)*r+x,
Math.sin(Math.PI/4)*r+y);
mc.curveTo(Math.tan(Math.PI/8)*r+x, r+y, x, r+y);
mc.curveTo(-Math.tan(Math.PI/8)*r+x, r+y, -Math.sin(Math.PI/4)*r+x,
Math.sin(Math.PI/4)*r+y);
mc.curveTo(-r+x, Math.tan(Math.PI/8)*r+y, -r+x, y);
mc.curveTo(-r+x, -Math.tan(Math.PI/8)*r+y, -Math.sin(Math.PI/4)*r+x, -
Math.sin(Math.PI/4)*r+y);
mc.curveTo(-Math.tan(Math.PI/8)*r+x, -r+y, x, -r+y);
mc.curveTo(Math.tan(Math.PI/8)*r+x, -r+y, Math.sin(Math.PI/4)*r+x, -
Math.sin(Math.PI/4)*r+y);
