Hi,

The following example demonstrates a rather unexpected result:

>>> import numpy
>>> x = numpy.array( complex( 1.0 , 1.0 ) , numpy.object )
>>> print x.real
(1+1j)
>>> print x.imag
0

Shouldn't real and imag return an error in such a situation?

Thanks,
Mike

Don't use 'numpy.object'. Because complex is a numerical type, numpy can handle it just fine. By setting dtype to numpy.object, numpy then treats it like an object rather than a numerical.

x = numpy.array( complex(1.0, 1.0) )

should work just fine.

I hope that helps!
