For complex floating-point operands, real-valued floating-point special cases must independently apply to the real and imaginary component operations described in the above table. For example, let ``a = real(x1_i)``, ``b = imag(x1_i)``, ``c = real(x2_i)``, ``d = imag(x2_i)``, and

- Similarly, if ``b`` is ``+0`` and ``d`` is ``-0``, the imaginary component of the result is ``+0``.
