| random | () | method |
public static function random(min:Number, max:Number, decimalPlaces:int = 0):NumberReturns a random number between a range.
Parameters
min:Number — the begin of the range.
| |
max:Number — the end of the range.
| |
decimalPlaces:int (default = 0) |
Number — a random number between the range (min, max).
|
ArgumentError — if the max argument is less than the min argument.
