Calculation of 𝜋 to 100,000 decimals

Abstract

At that time a computation of x to 1,000,000D will not be difficult.* We have computed 1/ir by (6) to over 5000D in less than a minute.t We have computed e on a 7090 to 100,265D by the obvious program.This takes 2.5 hours instead of the 8-hour run for t by (2).■
