Hmmm... http://www.lacim.uqam.ca/plouffe/Simon/articlepi.html seems broken, but http://www.stud.enst.fr/~bellard/pi/pi_n2/pi_n2.html still works for me. -- Clive Tooth http://www.pisquaredoversix.force9.co.uk/ End of document ============================================================================== From: "Doug Gwyn (ISTD/CNS) " Subject: Re: Proposal: Inexpensive Method of "True Random Data" Generation Date: Tue, 9 Nov 1999 16:06:00 GMT Newsgroups: sci.math,sci.misc,sci.physics,sci.crypt jsavard@ecn.ab.ca wrote: > Now _that's_ news. Or at least it was in 1997. The original decimal-digit post-Plouffe article was: http://www.lacim.uqam.ca/plouffe/articlepi.html There have been further improvements, but I haven't been tracking them. Over 200 billion decimal digits of Pi have been computed at the University of Tokyo, so for most practical purposes one can simply use table look-up!
