Since every iteration calls the Incomplete Gamma function which is a bit slow for arguments > √3, a faster simplified approach could be used that only applies the first guess to the random number. At least for the suggested application in games this should be sufficiently exact. But the Normal guess routine is not exposed to the user so the suggested method is not applicable. At least not directly. ;) Dieter
