Floating Exception Core Dumped
as a result I'm current trying to make this code take a number and test if it is prime or not. Now then before I get to troubleshoot the function it gives me the error "floating point exception" right after inputting the number. Here's the code: int main() { int input; cout << "Enter number: " << endl; cin>> input; int i = input/2; int c; for (i>0; i--;) { c= input%i; if (c==0 || i == 1) cout c floating point exception 8 << "not prime" << endl; else cout << "prime" << endl; } return 0; } so essentially why is it giving me a floating point exception and what does that even mean? c++ floating-point share|improve this question edited Oct 21 '12 at 20:57 Ian Kemp 11.6k84976 asked Nov 21 '10 at 7:21 Samuraisoulification 95262553 4 Something is wrong with your for loop. –Lazer Nov 21 '10 at 7:24 the floating point exception has many reasons but depending on your code, I do agree with Pete and I think c= input%i; is the cause of the problem and I hope my answer helps you.. –TopDeveloper Nov 21 '10 at 7:38 add a comment| 3 Answers 3 active oldest votes up vote 21 down vote accepted A "floating point number" is how computers usually represent numbers that are not integers -- basically, a number with a decimal point. In C++ you declare them with float instead of int. A floating point exception is an error that occurs when you try to do something impossible with a floating point number, such as divide by zero. share|improve this answer answered Nov 21 '10 at 7:26 Crashworks 28.1k764145 Okay, well let me make sure I understand my own code before I try to fix it. The for lop will only execute if i > 0 right? Then the only time it will divide later is c= inpu

is unclear or undesirable. Exceptions can be ignored, in which case some default action is taken, such as returning a special value. When trapping is enabled for an exception, a error is signalled whenever that exception occurs. These are the possible floating point exceptions: :underflow This exception occurs when the result of an operation is too small to be represented as a normalized float in its format. If trapping is enabled, the floating-point-underflow condition is signalled. Otherwise, the operation results in a denormalized float or zero. :overflow This exception occurs when the result of an operation is too large to be represented as a float in its format. If trapping is enabled, the floating-point-overflow exception is signalled. Otherwise, the operation results in the appropriate infinity. :inexact This exception occurs when the result of a floating point operation is not exact, i.e. the result was rounded. If trapping is enabled, the extensions:floating-point-inexact condition is signalled. Otherwise, the rounded result is returned. :invalid This exception occurs when the result of an operation is ill-defined, such as (/ 0.0 0.0). If trapping is enabled, the extensions:floating-point-invalid condition is signalled. Otherwise, a quiet NaN is returned. :divide-by-zero This exception occurs when a float is divided by zero. If trapping is enabled, the divide-by-zero condition is signalled. Otherwise, the appropriate infinity is returned. Raymond Toy Mon Jul 14 09:11:27 EDT 1997
