HugeMotherFuckingInt

I'm trying to write a HugeMotherFuckingInt processing library in C.

My first try, I stored the numbers as a char[] and computed them using basic arithmetic.

My second try, I stored the numbers as unsigned long char[]. This proved to be a faster, easier and clearer approach.

Still though, it seems to be a bit too slow.

What other data structures might result in faster execution of basic arithmetic +/*-?

Also, are there any algorithms to speed up the arithmetic operations themselves?

You should not use max(a, b) as it generates a conditional jump, it is sufficient to test that c < a because b < 2^32.
