How different programming languages handle divisio

Question

Perhaps this is the wrong sort of question to ask here but I am curious. I know that many languages will simply explode and fail when asked to divide by 0, but are there any programming languages that can intelligently handle this impossible sum - and if so, what do they do? Do they keep processing, treating 350/0 as 350, or stop execution, or what?

Answer 1

The INTERCAL standard library returns #0 on divide by zero

Answer 2

Most SQL implementations raise a "division by zero" error, but MySQL just returns NULL

Answer 3

The little-known Java programming language gives the special constant Double.POSITIVE_INFINITY or Double.NEGATIVE_INFINITY (depending on the numerator) when you divide by zero in an IEEE floating-point context. Integer division by zero is undefined, and results in an ArithmeticException being thrown, which is quite different from your scenario of "explosion and failure".

Answer 4

i'd be surprised if any language returns 350 if you do 350/0. Just two examples, but Java throws an Exception that can be caught. C/C++ just crashes (i think it throws a Signal that can probably be caught).
