static function Math.random() → Float

static function Math.random(Float high) → Float

static function Math.random(Float low, Float high) → Float

Generates random numbers.

If no parameters are provided, it will return a float in the range between zero and one.

If only one parameter is passed to the function, it will return a float between zero and the value of the high parameter. For example, random(5) returns values between 0 and 5 (starting at zero, and up to, but not including, 5).

If two parameters are specified, the function will return a float with a value between the two values. For example, random(-5, 10.2) returns values starting at -5 and up to (but not including) 10.2. To convert a floating-point random number to an integer, use the Math.floor() function.
