> (0e0).WHICH Num|0 > (-0e0).WHICH Num|-0 > 0e0 === -0e0 True These two Num values are distinct: they are the floating-point signed zeroes, which have different numeric behaviour in some situations. The .WHICH values correctly distinguish them. The === operator is incorrect in saying that they are the same object. The same problem arises with Complex numbers with zero real or imaginary parts: > <-0+0i>.WHICH Complex|-0|0 > <0+0i>.WHICH Complex|0|0 > <0-0i>.WHICH Complex|0|-0 > <-0-0i>.WHICH Complex|-0|-0 > <-0+0i> === <0+0i> === <0-0i> === <-0-0i> True -zefram
