Floating Point Exception (core Dumped)
case some default action is taken, such as floating point exception 8 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 http://www.cfd-online.com/Forums/cfx/25194-error-floating-point-exception-overflow.html 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 http://www.umiacs.umd.edu/~resnik/ling645_sp2002/cmu_manual/node19.html 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

Задача состоит в моделировании истечения газа из баллона через сопло. избыточное давление в floating point баллоне по сравнению с внешней средой 2 атм. Газ - воздух. Знаю, что проблема в сетке. Как лучше всего сделать сетку в данной задаче чтобы исследовать пограничный слой и срыв потока в начале сопла(если он floating point exception есть)? Я использовал метод edge sizing со сгущением к стенкам, но с моей сеткой происходит floating point overflow. Если делаю сетку автогенерацией с очень маленьким количеством клеток, то эта ошибка исчезает. Хочется получить эффект охлаждения газа при истечении из баллона.

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 << "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 11.5k84976 asked Nov 21 '10 at 7:21 Samuraisoulification 94762553 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.
