That question provides several pointers to big-integer libraries, etc. In what sense is that insufficient? – Oliver Charlesworth Jul 22 '15 at 01:32

BigInteger is a class in the standard Java libraries. For C, you want to use GMP.

I haven't used it much myself, however there is plenty of documentation at the provided link, particularly the chapter on [integer functions](https://gmplib.org/manual/Integer-Functions.html). – dbush Jul 22 '15 at 01:49
