If you wanted to implement such a beast, you could use something like intDivEx in the following program (using the overflow variant): and you can see it throws and catches the exception (leaving the return variable untouched) for the divide by zero case. The integer division raises a processor exception, whereas the flaoting point division has a representation. They are defined in @JeremyFriesner: There is no one definition of arithmetic. 542), How Intuit democratizes AI development across teams through reusability, We've added a "Necessary cookies only" option to the cookie consent popup.
