Problem w/ Math.random() in AS3

programming flash
1

To anyone who’s been playing with AS3…Here is my code

package {
    import flash.display.Sprite;
    import flash.text.*;

    public class RandomTester extends Sprite
    {
        public function RandomTester()
        {
            var txt:TextField = new TextField();
            txt.autoSize = TextFieldAutoSize.LEFT;
            txt.wordWrap = true;
            var output:String = ""
            
            for(var i:int = 0; i < 50; i ++) {
                output += (Math.random() *  100).toString() + "||" + "
";
            }
            txt.text = output;
            addChild(txt);
        }
    }
}

The textfield is there just because I can’t seem to get trace to work. Anyway, I keep getting identical sets of random numbers. Running the same .swf again and again, I get a few different sets of the SAME numbers . Does this have something to do with the way the random function is seeded? The docs say that the random number is calculated in an “undisclosed manner”. I am stumped. thanks in advance!
