The BBP formula gives rise to a spigot algorithm for computing the nth base-16 (hexadecimal) digit of π (and therefore also the 4nth binary digit of π) without computing the preceding digits. This does not compute the nth decimal digit of π (i.e., in base 10). [3]
One important application is verifying computations of all digits of pi performed by other means. Rather than having to compute all of the digits twice by two separate algorithms to ensure that a computation is correct, the final digits of a very long all-digits computation can be verified by the much faster Bellard's formula. [3] Formula:
Simon Plouffe (born June 11, 1956) is a French Canadian mathematician who discovered the Bailey–Borwein–Plouffe formula (BBP algorithm) which permits the computation of the nth binary digit of π, in 1995. [1] [2] [3] His other 2022 formula allows extracting the nth digit of π in decimal. [4] He was born in Saint-Jovite, Quebec.
Finds a formula that allows the nth hexadecimal digit of pi to be calculated without calculating the preceding digits. 28 August 1995 Yasumasa Kanada and Daisuke Takahashi: HITAC S-3800/480 (dual CPU) [36] [37] 56.74 hours? 4,294,960,000: 11 October 1995 Yasumasa Kanada and Daisuke Takahashi: HITAC S-3800/480 (dual CPU) [38] [37] 116.63 hours ...
While the PiHex project calculated the least significant digits of π ever attempted at the time in any base, the second place is held by Peter Trueb who computed some 22+ trillion digits in 2016 and third place by houkouonchi who derived the 13.3 trillionth digit in base 10.

The Chudnovsky algorithm is a fast method for calculating the digits of π, based on Ramanujan's π formulae.Published by the Chudnovsky brothers in 1988, [1] it was used to calculate π to a billion decimal places.
