Currently I'm learning about floating point exceptions. I'm writing a loop with a function. In that function a value is calculated that equals 0.5. As the loop proceeds, the input value gets divide...

I like to run my code with floating point exceptions enabled. I do this under Linux using: feenableexcept( FE_DIVBYZERO | FE_INVALID | FE_OVERFLOW ); So far so good. The issue I am having, is that...

Why was SIGFPE used for integer arithmetic exceptions, such as division by zero, instead of creating a separate signal for integer arithmetic exceptions or naming the signal in the first place for ...

I am newbie on the Linux signals, please help. The following code get core dump when run in Linux 2.6 gcc. $ ./a.out Floating point exception (core dumped) The questions: 1. Since a process signa...

I read this and this. The quintessence is that one can throw a SIGFPE if a nan is produced by including fenv.h and enabling all floating point exceptions but FE_INEXACT by feenableexcept(FE_ALL_EXC...

I have a several-thousand-line application that relies on SIGFPE (handled by a function pointer passed to signal()) to change state and have the code run correctly when certain floating point condi...

well, I have searched the articles about SIGFPE ,then I wrote a few tests but it's behavoir is strange. Then I have to post it here to ask for help. Is the GCC/G++ or ISO C++ clearly defined what h...

I am trying to build a simple C program for two different Linux environments. On one device the program runs fine, on the other device the program generates a floating point exception. The program ...

I have a program which deliberately performs a divide by zero (and stores the result in a volatile variable) in order to halt in certain circumstances. However, I'd like to be able to disable this ...

I have a small program performing floating-point division by zero, so I expect SIGFPE. #include <sys/types.h> #include <signal.h> #include <stdio.h> #include <stdlib.h> #in...
