There are two even less harmful solutions: (1) Raise an exception.  (2)
Provide the user with a top-level flag to control whether the attempt to
downcast a NumPy complex to a float should be handled by raising an
exception, by throwing away the imaginary part, or by taking the magnitude.

P.S. As things stand now, I do not regard NumPy as a reliable platform for
scientific computing.
