The problem with this is that a/0 is impossible, so when the zeros are "cancelled," what's really getting cancelled (on the left side) (along with the zero we added) is a part of an impossible number. To learn more, see our tips on writing great answers. You act like having something undefined is just an arbitrary thing mathematicians do, it is not at all. For example. $$x=a/b$$ means solve the following equation for ##x##:$$bx=a$$If ##b=0## then that equation has no solution. A C implementation may or may not conform to IEEE. C11 6.5.5 paragraph 5: The result of the / operator is the quotient from the division of the first operand by the second; the result of the % operator is the remainder. { It cannot be that 0/0 is 0, 1, and because that violates the rules of math, which depend on consistency. How to handle all errors, including internal C library errors, uniformly, http://rosettacode.org/wiki/Detect_division_by_zero#C. (There are some useful signals which are very useful in general in low-level programming and don't cause your program to be killed right after the handler, but that's a deep topic).

Note that the value stored in fexcept_t bears no resemblance to Here, inside the try block, the IndexOutofRangeException exception is not raised hence the corresponding catch block doesn't handle the exception. Division by zero leads to undefined behavior, there is no C language construct that can do anything about it. Suspicious referee report, are "suggested citations" from a paper mill? DivideByZeroException uses the HRESULT COR_E_DIVIDEBYZERO, which has the value 0x80020012. If substituting a value into an expression gives 0/0, there is a chance that the expression has an actual finite value, but it is undefined by this method. remainder. | MT-Safe dependent.

You should however note that the signal handling is OS-dependent and MinGW somehow "emulates" the POSIX signals under Windows environment. The catch block catches the exception of type Exception, displays the message Exception occurred and then calls the what function. We define the Division function that calls the constructor of class Exception when denominator is zero otherwise returns the quotient. from a set of calculations, you should clear all the flags first. Your best bet is to not divide by zero in the first place, by checking the denominator. by calling feclearexcept. C++ does not handle divide-by-zero as an exception, per-se.
