Details
I would like to be able to use complex numbers through pythonnet. To achieve this, encoders/decoders should translate between a PyComplex class based on thehttps://docs.python.org/3/c-api/complex.html#c.PyComplex_Type and the System.Numerics.Complex class.
I created a minimal class to create a System.Numerics.Complex from real and imaginary parts and return it to Python and to print a System.Numerics.Complex passed to a function (see attached source code).
I compiling the solution and copied the resulting dll into a
Complexfolder with the__init__.pyandclr_runtime.jsonfiles in the attached zip file.I ran ipython in the directory containing
Complexand ran the following commands:
