Thèmes de recherche

Bailey's research has included studies in parallel numerical algorithms, fast Fourier transforms, super-computer performance and computational number theory.

In 1996, with Peter Borwein and Simon Plouffe, David Bailey discovered a new formula for pi. This formula permits one to compute the n-th binary or hexadecimal digit of pi, without computing the first n-1 digits, by means of a simple scheme that requires very little memory and no multiple precision software. More recently, Richard Crandall and him have shown that there is a connection between the new pi formula and the centuries-old question of normality (ie, statistical randomness of digits in a certain sense) of pi and various other math constants.
