Is it possible to differentiate between 0 and -0?

Question

I know that the integer values 0 and -0 are essentially the same. But, I am wondering if it is possible to differentiate between them.

For exam

Answer 1

For an int (in the almost-universal "2's complement" representation) the representations of 0 and -0 are the same. (They can be different for other number representations, eg. IEEE 754 floating point.)
