Do you mean rand()%max specifically in the case of the C function rand ()? Or using %max on any random number generator in general. If the first case, I totally agree, and I found out that from experience first, then googling second :) But if the latter, I wasn't aware that all RNGs were bad at randomizing the lower bits, so could you explain why? It's also possible that Lionello meant the latter case as well. -Steve
