BigInt for C++

Правка en3, от Arpa, 2016-01-03 14:48:39

Hi!

One of the C++ programmers problems is to save integers more than '2^64-1'(we can save 0 to 2^64-1 in unsigned long long int).

It is the best bignum I ever have seen: Link.

  1. It has operation: + , - , / , * , % , ^(pow) , gcd , lcp , abs.

  2. Can work with ostream(cout), istream(cin).

  3. Can convert to long long, string.

  4. It uses fast multiplication.
