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 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

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));
}

"The following example returns a random number between two specified integers"

should read

Integer was introduced to ActionScript in version 3.0.
Since this is an AS2 example,
Number is correct. ActionScript 2.0 simply
uses Number for any type of
numeric value.
