.5), the value is rounded up to the next higher integer.
Example
The following example returns a random number between two specified integers.
function randRange(min:Number, max:Number):Number {
var randomNum:Number = Math.round(Math.random()*(max-min))+min;
return randomNum;
}
for (var i = 0; i<25; i++) {
trace(randRange(4, 11));
}

Returns
A number; the sine of the specified angle (between -1.0 and 1.0).
Description
Method; computes and returns the sine of the specified angle in radians. To calculate a radian, see

Example
The following example draws a circle using the mathematical constant pi, the sine of an angle,
and the Drawing API.
drawCircle(this, 100, 100, 50);
//
