Divide by Zero Exception in C++This video shows how to handle divide by 0 exceptions in C++, I am using Dev C++ IDE. The C standard explicitly states that dividing by zero has undefined behavior for either integer or floating-point operands. $$x=a/b$$ means solve the following equation for ##x##:$$bx=a$$If ##b=0## then that equation has no solution. But it might have raised a question in your brain. Not only the division by zero but also parsing errors. Others say that 0/0 is obviously one because anything divided by itself, just like 20/20 is 1. catch(Exception e) Dividing a number by Zero is a mathematical error (not defined) and we can use exception handling to gracefully overcome such operations. All Rights Reserved. Remarks. } The Division function calculates the value of quotient {if non-zero value of denominator was passed} and returns the same to the main. divide by zero exception. A division by zero is a mathematical oddity, , if a computer or calculator etc performs a 1\0 they would crash, the OS prevents the execution, and displays ERROR or UNDEFINED, , , some versions of windows calculator display positive or negative infinity, , try it. If ##1/x## is the number you have to multiply ##x## by to get ##1##, what would that mean for ##1/0##? No, it can be anything. This will not trigger a software exception, but it can (depending on the target CPU) trigger a Hardware Exception (an Integer-Divide-by-Zero), which cannot be caught in the traditional manner a software exception can be caught. (a. if (a-b!=0) then calculate the value of d and display.b. Catching those signals is only useful for debugging/diagnosing purposes. When we divide something by zero, the result will be infinite.

Jordan's line about intimate parties in The Great Gatsby? In CheckDenominator function we check if denominator is zero, if true throw an exception by passing a string Error. It could also format your hard disk and laugh derisively :-). In my opinion, it seems that 0/0 could be equal not only to 0 and/or 1, but actually to any number. This function restores the flags for the exceptions indicated by FPUs report all the different exceptions. // code that may raise raise an exception Can undefined cases even exist? Direct link to Collin's post All three work, and there, Posted 5 years ago. They are defined in fenv.h.
