(in)exactness of complex numbers

[Skip Montanaro]

Once these numeric changes are all implemented, if I define a complex
constant with either integer real or imaginary parts, e.g.
    
    c = 1+2.1j

    d = 1.2+5j

    e = 4+7j

should I get an integer back (exact) or a float (inexact) when asking for an
attribute that was originally an integer?  In general, can complex numbers
be considered to have two exactness attributes?
