   Representing EXTREMELY large numbers in C++
  Hypothetically, if you wanted to represent numbers with more than say, oh, 10 million digits on a computer, what would be the most effective and clean way of doing it? This is a rather odd question, i realise this, but i was just wondering how to do it.   
  Use a bignum/arbitrary precision library like  GMP.   ;  Wow, that was fast SiCrane! Thanks a ton for this.
