Python has native support of complex numbers, something the C# language is lacking as well. Converting complex results to and from NumPy is not implemented at all (yet). Please step forward if you want to work on this.

The function fft(...) in numpy.fft and random(...) in numpy.random had to be renamed because C# doesn't allow a member to have the same name as its enclosing class. That's why in Numpy.NET these functions have been renamed with a trailing underscore like this: `np.fft.fft_(...)`
