Hi Friends,
I am trying following code
int main(void)
{
try
{
int i,j,k;
i=10;
j=0;
k= i/j;
}
catch(...)
{
printf("Erro!~" );
return 1;
}
return 0;
}
Here it's divide by Zero error.
Now using MSVC compiler. the code flow lands up in catch block.
but gcc comiler the code simply throws "floating point exception"
can terminates.
Any comments?? 5 7592

The behavior on a division by zero is undefined. So anything can happen. The
exception that gcc mentions is not a C++ exception, but rather a CPU
exception.

What you are saying is true. So If I want to write an application which
should be capable ot resuming the execution. What I need to do ? I am
targeting windows,Redhat and solaris platforms.

Check if they are zero before doing the division and throw your own
exception.
Note that if you divide doubles it will not throw an exception if the
divisor is 0.0 but will return a NaN type. (Infinity or Negative
Infinity).

Maybe just use an if-statement to test if 'j' is 0? You can recover in the
if-statement or throw an exception and recover in the catch-block?

MSVC is fooling you a little bit. It does not throw C++
exceptions, but rather "structured exceptions". Only because
you're using the ellipsis (...) form of catch are you getting
the exception.
Linux and UNIX like systems use "signals" to indicate problems.
You need to create a signal handler. Modern versions of the
gcc compiler allow you to throw an exception from the signal
handler.

I have a query that calculates various using variables from a survey
database. As with any survey, there are many instantces of null values. I'm
wondering if there is any way to escape the error caused by dividing by zero
or null values. The specific message i get is:
ERROR: floating point exception! The last floating point operation either
exceeded legal ranges or was a divide by zero

Can anyone tell why the query below would throw a divide-by-zero
error? The only reason I can see for the error happening would be if
SUM() came out to be zero, but this never happens with the
data I'm using. SOME of the values in the EXP_NET column are zero, but
the sum itself is always non-zero.
The query is:
TRANSFORM SUM(-)/SUM()*100 AS DATA SELECT

Dear all,
Assume I have two big arrays A and B. And I want to element-wise divide
A by B. When an element of B is zero, the results are also zero.
Such as A = { 2, 4, 0, 6}
B = { 1, 0, 0, 2}

R = { 2, 0, 0, 3}

Hello! I was working on some code the other day, and I came across an odd
discrepancy between the decimal and the double type.
If I attempt to divide a decimal by zero, the framework throws an error.
If I attempt to divide a double by zero, the framework returns infinity.
From a mathematical standpoint, it would seem to me that the decimal handles
this division correctly, while the double's handling of this is flawed.
Is there a...

Hi,
I have created a report in my Access db which has two columns - I'll call them Number1 and Number2. I have added a textbox to calculate a percentage from these two numbers
=(/) with the format property set as percentage.
My problem. Sometimes the number in Number2 is a zero, which means the result of the expression is invalid and gives me "#Num!" - I understand why this is happening, but I wondered if there was a way around it....

How do I divide by zero on my form (in a text box).
That is, how do I carry out a division problem when the denominator is

Hello folks,
I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".
The problem is that using the GNU compilers, it seems that the internal comparison operator "<=>" tries to promote arguments from unsigned to signed.
This is as boiled down as I can make it.

Windows 11 and 10 have less user interface control over operating system update behaviour than previous versions of Windows. In Windows 11 and 10, there is no way to turn off the Windows Update option using the Control Panel or Settings app; it automatically checks for updates and installs any it finds, whether you like it or not. For most users, this new feature is actually very convenient. If you want to control the update process,...
