  1. #DidYouKnow: The #Chudnovsky #Algorithm is a fast method for calculating the digits of π, based on #Ramanujan's π formulae. It was published by the Chudnovsky brothers in 1988.

    It was used in the world record calculations of 100 trillion digits of π on March 21, 2022.

    It does diverge. It has no sum.
    However, the uniquely valued #Riemann #ZetaFunction can be analytically continued into the left half-plane where we find zeta(-1)=-1/12 (which 'looks like' 1+2+...). #Cesàro #summation will get you part of the way there also, and, as you say, yields the same result; presumably due to some ultimate cosmic logical rightness :-)
    I very strongly recommend BP's superb exposition of this issue
