Decimal digits in $\pi$

183 Views Asked by At

Around ten years ago I had read somewhere that there was a question in an exam for application for software engineer position in a big company which states: "What is the one billionth digit of $\pi$?" Can we predict the $n$th digit of $\pi$ without knowing any preceding digits at all?

Yes, if the recently (January 2022) posting by Simon Plouffe is correct. He claims a method he discovered can retrieve individual decimal digits of pi without needed any previous digits.
