Hello, the only known way is to use Bellard formula or mine, this is in binary or base 16. there is a way in base 10, I have found a procedure in 1996 but the time is way too big : at least O(n^3), i.e. not practical. The reasonable reachability is 1000000 , Best regards, Simon Plouffe Le 2019-03-15 à 02:29, Richard Hess a écrit :
