Big Number C (BigNumberC)

The Big Number C library is a C library for arbitrary precision arithmetic. It can be used to perform arithmetic operations on numbers of arbitrary size. It is written in C and is designed to be portable and efficient. You can work with numbers of any size, and the library will automatically allocate memory as needed.
