... A continued fraction result would avoid this objection, and might actually be mathematically useful. The only such calculation I'm aware of was the one by RWG some 30 years ago that found 17 million terms.
In 1985. I, for one, was inspired by his effort. In June 1999, Mathematica spewed out 20 million terms for me on my personal computer and in October 2000, 53 million terms. And if I could up that number (alas, my current machine is seven years old), I would. ;) _______________________________________________ What pi algorithm did you use, arctan, AGM, Ramanujan's 1/pi, etc?
