and this is the program too :

#include "stdafx.h"
#include <iostream>

using namespace std;

int _tmain(int argc, _TCHAR* argv[])
{
long double sum = 1;

for (int t=1 ; t<200 ; t++)
{
sum = sum * t;
cout<<t<<"\t\t"<<sum<<"\n";
}
}

You have to create your own type to go any higher than that.

a long double would be your best bet here wouldn't it?

You have to create your own type to go any higher than that.

i went to your link but there aren't new types , there was only long long that tested ...

you talking about new type of variable ?!! like struct or class ? or some thing else ?!
how ?!!

a long double would be your best bet here wouldn't it?

on top pic that i uploaded , u can see result with long double , last night i try with unsigned long double but the result was same as long double ....
