Fast method for calculating the digits of π
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, it was used to calculate π to a billion decimal places.

From Wikipedia
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, it was used to calculate π to a billion decimal places. It was used in the world record calculations of approx. 2.7 trillion digits of π in December 2009, 10 trillion digits in October 2011, around 22.4 trillion digits in November 2016, 31.4 trillion digits in September 2018–January 2019, 50 trillion digits on January 29, 2020, 62.8 trillion digits on August 14, 2021, 100 trillion digits on March 21, 2022, 105 trillion digits on March 14, 2024, and 202 trillion digits on June 28, 2024. Recently, the record was broken yet again on November 18, 2025 with 314 trillion digits of pi. This was done through the usage of the algorithm on y-cruncher.
