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. [2]
The last 100 decimal digits of the latest world record computation are: [1] 7034341087 5351110672 0525610978 1945263024 9604509887 5683914937 4658179610 2004394122 9823988073 3622511852 Graph showing how the record precision of numerical approximations to pi measured in decimal places (depicted on a logarithmic scale), evolved in human history.
BBP and BBP-inspired algorithms have been used in projects such as PiHex [5] for calculating many digits of π using distributed computing. The existence of this formula came as a surprise. It had been widely believed that computing the nth digit of π is just as hard as computing the first n digits. [1] Since its discovery, formulas of the ...

Pi can be calculated with any number of digits – for larger calculations, a lot of RAM is necessary. In this case, 25 billion digits of Pi are calculated in 10.4 minutes. y-cruncher has the following characteristic properties: [9] [10] Multithreading; Vector instruction sets (see SIMD) Swapping; Using multiple hard drives (in RAID)
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.
Pi Day is celebrated each year on March 14 because the date's numbers, 3-1-4 match the first three digits of pi, the never-ending mathematical number. "I love that it is so nerdy. We are pi nerds ...
QuickPi by Steve Pagliarulo for Windows is faster than PiFast for runs of under 400 million digits. Version 4.5 is available on Stu's Pi Page below. Like PiFast, QuickPi can also compute other irrational numbers like e, √ 2, and √ 3. The software may be obtained from the Pi-Hacks Yahoo! forum, or from Stu's Pi page.
