-Given a complex number ``z`` for which ``z.imag/z.real`` underflows to zero,
-the :func:`cmath.phase` of ``z`` should not raise ``OverflowError``.  Also,
-given arguments of zero, Python's :func:`math.atan2`, :func:`math.atan2pi`,
-and :func:`cmath.phase` should return the values specified by Annex F of the
-C standard, not raise ``ValueError``, regardless of whether the platform's
-math library sets ``errno`` for ``atan2(0.0, 0.0)``, ``atan2(0.0, -0.0)``, etc.
