Simon Plouffe
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 digit of π, in 1995.<ref>Template:Gutenberg author; accessed March 23, 2015.</ref><ref>BBP algorithm, arxiv.org; accessed March 23, 2015.</ref><ref>Template:Cite web</ref> His other 2022 formula allows extracting the nth digit of Template:Pi in decimal.<ref>Template:MathWorld (referencing Template:ArXiv)</ref> 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 integer sequences 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.<ref>Template:Citation</ref>
