You need to use the / operator, if you want to do floating-point division.
Yes, exactly, integers don't have +-0 and +-infinity... only (obviously) a kind of nan.
No, failure (exception, bottom) is different from NaN, which is just another value in the domain - admittedly one which behaves rather strangely.
Said differently: I don't know a thing about floats or numerics.
Perhaps it helps to think of floating point values as intervals? If +0 means some number between 0 and the next possible representable number (and similar for -0), it may make more sense to have 1/+0 and 1/-0 behave differently. -k -- If I haven't seen further, it is by standing in the footprints of giants
