#randomrange (predefined symbol)

This predefined symbol returns the maximum value that can be returned by the random function + 1. Divide the return value of the random function by #randomrange to obtain a random floating-point number between (but not including) -1 and 1.

To obtain a random value between 0 and (but not including) 1, use the abs function to convert the return value of the random function to a positive number before dividing it.

Example:

; calculate a random float between 0 and 1
float x = abs(random(1234)) / #randomrange
