Problems with mod

[John Smith]

I'm using Microsoft Visual C++ 6.0. I've been having trouble with my %
operator in my code; it doesn't seem to be working correctly. As a test I
typed the following in the Visual Studio quick watch window: "3400 % 1515".
This evaluated to 0x000009d6 (2518 in decimal). 2518 being larger then
1515, this is not only an inaccurate, but invalid result! Has anyone else
seen a simalar problem? Is there a patch or something I need to download?

Thanks IA

0x3400 % 0x1515 = 0x09d6

Show us the code, and we'll try to sort it out.

As a test I
typed the following in the Visual Studio quick watch window: "3400 % 1515".
This evaluated to 0x000009d6 (2518 in decimal). 2518 being larger then
1515, this is not only an inaccurate, but invalid result!

To me, "inaccurate" and "invalid" mean the same thing in
this case.

Has anyone else
seen a simalar problem?

Not I. I wrote and compiled the following with MSVC++ v6.0 SP5 :

#include <iostream>

int main()
{
std::cout << 3400 % 1515 << '\n';
return 0;
}

It gives the output:

370


When I pasted the expression '3400 % 1515' (without the
quotes) into a quick watch window and clicked the "Recalculate"
button, I got a result of 370. Perhaps you're having trouble
using your debugger, which is of course not topical here.

Is there a patch or something I need to download?

I believe the latest (and last) patch for MSVC++ v6.0
is "Service Pack 5", but I doubt this patch (or lack
of it) has anything to do with your problem (of course
I could be wrong, Microsoft has been known to do some
strange things. ).

result!

If 3400 and 1515 are hex numbers, the result is correct, that is

0x3400 % 0x1515 = 0x9d6

Has anyone else seen a simalar problem?

What problem?

Is there a patch or
something I need to download?

0x3400 % 0x1515 = 0x9d6

Yep, take your watch window out of Hexademcimal mode (right click on it).
