Simon Plouffe is a Canadianmathematician. He discovered the formula for the BBP algorithm which permits the computation of the n-th binary digit of pi, in 1995. Plouffe is also the co-author of the Encyclopedia of Integer Sequences, made into a web site dedicated to integer sequences later in 1995. The site is the On-Line Encyclopedia of Integer Sequences.
Plouffe discovered an algorithm for the computation of Pi in any bases in 1996.
Plouffe's Inverter is a web site that contains over 200 million mathematical constants.
