Simon Plouffe

Simon Plouffe (born June 11, 1956) is a French Canadianmathematician who discovered theBailey–Borwein–Plouffe formula (BBP algorithm) which permits the computation of thenthbinary digit ofπ, in 1995.[1][2][3] His other 2022 formula allows extracting thenth digit ofπ in decimal.[4] He was born inSaint-Jovite, Quebec.

He co-authoredThe Encyclopedia of Integer Sequences, made into the websiteOn-Line Encyclopedia of Integer Sequences dedicated tointeger 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.[5]
