Let complex print the correct signBit of its imaginary part in case of negativeZero.

Note: the signBit are not preserved upon reinterpretation.
That's a problem of representation via arithmetic operation 1 + 2 i
because we have this
0.0 - 0.0 -> 0.0
0.0 + (-0.0) -> 0.0
(-0.0) + (-0.0) -> -0.0
(-0.0) - 0.0 -> -0.0
