Bellard's formula

Bellard's formula, as used by PiHex, the now-completed distributed computing project, is used to calculate the nth digit of π in base 2. It is a faster version (about 43% faster[1]) of the Bailey–Borwein–Plouffe formula.

Bellard's formula was discovered by Fabrice Bellard in 1997.
