Hi list

Does anybody know after how many samples rand repeats? I seem to be getting very consistent loops of about 65,000 samples length. Am I right in assuming that rand repeats after 65,536 samples? If so, are there other random number generators with a longer period?

Thanks,

Alex

Could have sworn I read the manual... Oh well, another case of RTFM. Thanks, Joachim and Oeyvind!

Out of curiosity: why is it 31 instead of 32 bits?

yes. and there is also an optional parameter in rand. the manual says:
"isel (optional, default=0) -- if zero, a 16-bit number is generated. If non-zero, a 31-bit random number is generated. Default is 0."

Perhaps rnd31 ?
