> amount of roughly 10^160000000000000. You're also underestimating the accuracy by the absurd amount of roughly 10^202000000000000 ;) You need ~ zero of the digits of the calculated pi to do OPs calculation. [edit] My brains melting, I think I'm wrong and you are underestimating the underestimation of the accuracy by the absurd amount of roughly 10^42000000000000. OP is underestimating by 10^202000000000000.
