Could you give me an "algorithm" to see the difference? Which 32-bit pseudo random number generator (PRNG) did you use, and which 64 bit PRNG, where you saw that difference? I hope, my questions don't sound provocative - I am really interested. Perhaps some contributors to this thread may find http://stat.fsu.edu/~geo/diehard.html interesting. There are a lot of tests for the "randomness" of PRNGs, and it is pretty easy to try out your own favorite PRNG with those tests. However, interpreting the results may need some statistical knowledge. Regards, Dieter
