I am trying to achieve arbitrary precision for the C++ program below. It works
only to about two digits (integer 50) on the C++ compiler I used a few days ago.
I am trying to implement the MAPM arbitrary precision library for 300000000
(three hundred million) digits. Any other method or precision greater than
200000 (two hundred thousand) digits will be helpful, but the one below is
best, unless a better method can...
