Somebody asked me how absolute value of a real number can be defined. I said |a| is defined as +a if a>=0 and -a if a<0 (instead of, |a| is defined as a if a>=0 and -a if a<0). Then came an objection that with such a definition if a=0 its absolute value should be +0 and there's no such thing.
Can't one define -0 and +0 in integer number set such that +0=-0=0?
