Hard to say. 32-bit OS?? 64-bit OS ?? Windows?? Unix/Linux??Can you tolerate rounding??

Have you read a C++ book about sizeof and capacities of the built-in types??

Do you mean which variable type...like int or double?

Have you tried DWORD? I'm still somewhat new to C++, so I could very well be wrong, but I know I had to use it in a program I wrote last semester on the time it takes for different sorting algorithms to finish sorting because the time was greater than 2xxxxxxxx or something.

If you want to try it, you declare it just the same as you would an integer or a double.

ex: DWORD x

x = 10^1000

Hope this helps...

A DWORD is a Microsoft whiz-bang for a long.

[code=c]
typedef long DWORD;
