round (Math.round method)

Rounds the value of the parameter x up or down to the nearest integer and returns the value. If parameter x is equidistant from its two nearest integers (that is, the number ends in .5), the value is rounded up to the next higher integer.

Availability: ActionScript 1.0; Flash Lite 2.0 - 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

x:Number - A number.

Returns

Number - A number; an 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+1) + (min-.5));
    return randomNum;
}
for (var i = 0; i<25; i++) {
    trace(randRange(4, 11));
}
