i need to do %666013 ( this is a prime number ) from a very big number.
that very big number i get it with this formula:
S=S*(v[i]+1)+S;

the vector has like 1'000'000 numbers .. so the number will be quite big.

i think i ll need to find a better method rather than doing all the calculus..


and for nuclearsilo, those are for microsoft visual c++.
it doesn't work for borland c++.. i mean that _int64 won't work

There are many big integer libraries out there. Notably, I have used BigInt and GMP. The code in BigInt and GMP is designed to be cross-platform, so you shouldn't have problems deploying it in your programming environment.

EDIT:
Borland C++ sucks. Why would anyone still use that?

Just do all the calculations in mod (very big number). You will never exceed 6 digits.

We used to learn c++ on that in school, DOS mindset. :l

edit: shit, forgot to answer op... just off the top of my head, did you try "extended", or was that just for floating point operations? (I barely had a C in computer sciences class lol)
