David Bailey has a brief explanation of the Pi digit algorithm on his Web page at NERSC... http://hpcf.nersc.gov/~dhbailey/pi-alg Also check out "Recognizing Numerical Constants" by David H. Bailey and Simon Plouffe at... http://www.cecm.sfu.ca/organics/papers/bailey/paper/html/paper.html and click on the link titled "Formulas for Pi and Related Constants." More interesting stuff at... http://www.multimania.com/bgourevitch/ref/ottawaPi.pdf Where plouffe discusses some more of the math and reveals the 400 billionth binary digit of Pi. Lots more if you use a search engine. -- Eric Michael Cordian 0+ O:.T:.O:. Mathematical Munitions Division "Do What Thou Wilt Shall Be The Whole Of The Law"
