Where does boost python register from python converters for builtin types such as from PyLong_Type to double?
I want to define a converter that can take a numpy.float128 from python and returns a long double for functions in C++. I already did it the other way round, the to_python converter. For that I tweaked builtin_converters.hpp but I didn't find how boost python does the from python conversion.
The from python conversion is in fact done in builtin_converters.cpp and not in the header part of the library. I Copied this file and deleted everything except the converter for long double, which I was then able to modify.
