[Numpy-discussion] Change in the representation of complex numbers in NumPy 1.1

[Francesc Alted]

Hi,

I've seen that NumPy has changed the representation of complex numbers 
starting with NumPy 1.1.  Before, it was:

>>> numpy.__version__
'1.0.3'
>>> repr(numpy.complex(0))    # The Python type
'0j'
>>> repr(numpy.complex128(0))  # The NumPy type
'0j'

Now, it is:

>>> numpy.__version__
'1.2.0.dev5313'
>>> repr(numpy.complex(0))
'0j'
>>> repr(numpy.complex128(0))
'(0.0+0.0j)'

Not that I don't like the new way, but that broke a couple of tests of 
the PyTables suite, and before fixing it, I'd like to know if the new 
way would stay.  Also, I'm not certain why you have chosen a different 
representation than the Python type.

Thanks,
