Fast multiple precision exp(x) with precomputations
Résumé
What is the most efficient way to compute the exponential function when allowing for the precomputation of lookup tables? In this paper we study this question as a function of the working precision and analyze both classical and asymptotically fast approaches. We present new complexity results, discuss efficient parameter choices and point out improvements that lead to speedups over existing implementations.
