MACROMEDIA FLASH 8-FLASH LITE 2.X ACTIONSCRIPT LANGUAGE - Random (Math.random Method); Round (Math.round Method)

Math 425
random (Math.random method)
public static random() : Number
Returns a pseudo-random number n, where 0 <= n < 1. The number returned is a pseudo-
random number because it is not generated by a truly random natural phenomenon such as
radioactive decay.
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.
Returns
Number - A number.
Example
The following example outputs 100 random integers between 4 and 11 (inclusively):
function randRange(min:Number, max:Number):Number {
var randomNum:Number = Math.floor(Math.random() * (max - min + 1)) + min;
return randomNum;
}
for (var i = 0; i < 100; i++) {
var n:Number = randRange(4, 11)
trace(n);
}
round (Math.round method)
public static round(x:Number) : Number
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.

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.
