Not much. As 1.1^2=1.21, I would think this would then take 2 datapoints, not 4. If you take at each step n = 1.1^n (rounded up) n will stay at 2 forever. And first you talk about rounding down, later about rounding up. So what is it. Maybe you should give a better specification? -- Piet van Oostrum <p...@cs.uu.nl> URL: http://pietvanoostrum.com [PGP 8DAE142BE17999C4] Private email: p...@vanoostrum.org -- http://mail.python.org/mailman/listinfo/python-list
