The Miraculous Bailey-Borwein-Plouffe Pi Algorithm By Steven Finch, Research and Development Team, MathSoft, Inc. Overview: 10/1/95 David Bailey, Peter Borwein and Simon Plouffe have recently computed the ten billionth digit in the hexadecimal expansion of pi. They utilized an astonishing formula: which enables one to calculate the dth digit of pi without being forced to calculate all the preceding d-1 digits. No one had previously even conjectured that such a digit-extraction algorithm for pi was possible. Click here to see the original CECM announcement and here to see a description for a non-technical audience. Bailey, Borwein and Plouffe discovered their formula using the PSLQ lattice reduction algorithm. From Mathsoft.com
