Simon Plouffe

 ( 1956 Births ) 

Simon Plouffe (born June 11, 1956) is a Canadian mathematician who discovered the Bailey–Borwein–Plouffe formula (BBP algorithm) which permits the computation of the nth binary number digit of π, in 1995.; accessed March 23, 2015. BBP algorithm, arxiv.org; accessed March 23, 2015. His other 2022 formula allows extracting the nth digit of in decimal. (referencing ) He was born in Saint-Jovite, Quebec.

He co-authored The Encyclopedia of Integer Sequences, made into the website On-Line Encyclopedia of Integer Sequences dedicated to later in 1995. In 1975, Plouffe broke the world record for memorizing digits of π by reciting 4096 digits, a record which stood until 1977.
