Hi, out of curiousity, is it possible for a C++ integer (or long integer according to what i read) to go beyond 2,147,483,647? How do i attain it? do i need a certain library or piece of code to make it possible? Cheers.

You can also used unsigned long long if you need double the space. I think that trick let me do a project euler exercise without having to use the bigint library.

It's not really double the space; rather, the range starts at 0 instead of being centered on 0. But the size of the range remains unchanged.
