If both of the numbers are of type int like they stated then you'll get (On Visual C++ 6.0 and VC++ 2003)
#include "stdafx.h"
int main(int argc, char* argv[])
{
int x=1;
int y=9;
printf("%f\n",x/y); // The expression gets truncated before formatting
printf("%lf\n",x/y); // The expression gets truncated before formatting
printf("%f\n",(double)x/y); // The correct way when both are integers
printf("%lf\n",(double)x/y); // The correct way when both are integers
return 0;
}

Don't forget to make sure at least one of the components in the expression is a float or a double to avoid truncations. If both x and y are int's you will notice a truncation of the result before the printf formatting occurs.
printf("%f\n",(double)x/y);

See
<br />
double c;<br />
double x = 123.456;<br />
double y = 2.1;<br />
c=x/y;<br />
printf( "%f\n", c);

One slight correction: Use the "%f" format code for values of type float, and "%lf" format code for values of type double.

Do you want to create this utility or just need a tool for doing this
Somethings seem HARD to do, until we know how to do them.

I am already in the rocess of makin this utility ,but some ppl say that they move bad sectors in damaged floppies!! How can we do that? We can just indicate the OS that the sector is bad ,we cant move it here n there around.So I just wanted to confirm this thing. I hav tried my programs on several floppies n 8/10 hav been suceessfully repaired .But anyways Thanks .

Hey , Listen
CFlopy is just to read from a floppy , onthing else OK. It is not a floppy repairer . If u dont know the answer ,then stop guessing.

No, you listen. He suggested you look at an article related to your question. It might have had information that was useful to you, even though it didn't solve your problem directly. Your response is rude and uncalled for.

how can we detect bad sectors in a floppy??PLz tell with some implementation!!
|
|
|
|
|
Have you tried "chkdsk" command? It checks and fixes bad sectors on a drive.
- It's easier to make than to correct a mistake.

Is it possible to center align the subitem image (no text in subitem) in a List control (CListCtrl)? CListCtrl::SetItem() doesn't seem to do so. Help please!

1. Is there a way to get notification event/handler to window.ActiveXObject via IWebBrowser2 or any other Internet Explorer Library?
What I am trying to do here is recording the sent/received webmail. Before AJAX era, I utilized OnBeforeNavigate in WebBrowser Control to get notification event so I can capture the traditional webmail. But now with AJAX, since the top URL will not change when user click on "Inbox","Compose", the usual trick won't work and I think I need to inspect the data retrieved by XMLHTTP which means I need to have notification event for that. Do you know any way to do this for IE?
Thank you so much
