It makes error handling more difficult.
I think it's because in the first case you have floating-point overflow (which can happen not just in case of division by 0 and means some very-large number -- remember, you cannot distinguish 0 and 0.00..001) and in the second case it's just division by zero -- meaningless operation. -- Roman I.
