>TITLE: BUG: BINTOC(,8) and negative zero
>
>VERSION: 09.00.0000.1720
>
>EXPECTED: X=Y if and only if BINTOC(X,8)=BINTOC(Y,8)
>
>OBSERVED: 0.0=-0.0 and BINTOC(0.0,8)<>BINTOC(-0.0,8)
>
>NOTES: with this bug BINTOC(,8) is unusabled because
>any computation that it annuls a value has memory of the sign that had the value before being annulled.

>With 'B' conversion the problem remains
