--- Comment #4 from Anton Korobeynikov <asl at math.spbu.ru> ---
C++11 26.4.7.9:
Returns: The complex value corresponding to a complex number whose magnitude is
rho and whose phase angle is theta.

Obviously there is no complex number with negative magnitude. Returning NaN
looks a conforming behavior.
