The CDC Cyber series represents floating-point zero with the (12-bit)
exponent zero.  It doesn't matter whether the (48-bit) mantissa is zero
or not.  If you normalize such a number, though, I believe you get back
a mantissa of zero.

Integer zero is 60 bits of all zeros or all ones (1's-complement machine).
