2015-10-19 08:38:53 +0200 | answered a question | does SAGE compute Pi using Chudnovsky algorithm? Sage uses the mpfr library to compute pi to arbitrary precision. The mpfr algorithm apparently has a limit of 646456992 digits. Please refer to https://github.com/epowers/mpfr/blob/... Not sure if that is up-to-date, however. |
