I have written a program that handles signal for Floating point exception and I am using Ubuntu 10.4.
Here's my source code :

I am unable to catch floating exceptions (e.g. divide by 0 or 0/0) using the standard exceptions defined in stdexcept. What is the recommended way to catch such exceptions? Is the problem that no exception is thrown? An integer divide by zero will throw a system error, a floating point divide by error should return infinity ... |
Floating Point Exception, but I rounded everything with round(), baffled I have a problem with the below program which keeps giving me Floating Point Exception during runtime. When I asked someone for help, at first they told me to make sure I round my ints because I have some divisions with even and odd numbers. So I went through my code ... |

Floating Point Exception I have a code in which I enter a 12 or 13 digit number and it does a few calculations here and there, then it spits out the barcode again with a few extra details. When I enter a 13 digit number it works fine, and before I "fixed" my code, at least it was taking in a ... |

Hey guys, I've got the program to compile correctly, but every time I execute, it gives me the line says "Floating point exception"? Maybe my logic isn't correct or I code somewhere wrong? *EDIT: Well, I see the problem is the denominator can't be zero, and I correct that...and it runs now... But the output is not correct because it doesn't ... |

If I compile this with warnings turned up then it says the two for loops are statements with no effect. The goal of this is to keep calculating larger and larger prime numbers in a slow method until i press Ctrl+C, at which point it prints a report saying the largest prime found and how many numbers were checked. This is ... |
