Abstract:The currently best known algorithms for the numerical evaluation of hypergeometric constants such as ζ(3) to d decimal digits have time complexityFollowing work from Cheng, Gergel, Kim and Zima, we present a new algorithm with the same asymptotic complexity, but more efficient in practice. Our implementation of this algorithm improves slightly over existing programs for the computation of π, and we announce a new record of 2 billion digits for ζ(3).
