Py.IntSourceInterface for Python values of type Int if Python 2, Long if Python 3.
of_int i returns the Python int with the value i. Wrapper for PyInt_FromLong.
to_int o takes a Python int o as arguments and returns the corresponding 64-bit integer value. A Python exception (Py.E _) is raised if o is not a long. Wrapper for PyInt_AsLong.
of_int i returns the Python int with the value i. We have of_int i = of_int64 (Int64.of_int i).
to_int o takes a Python int o as arguments and returns the corresponding integer value. A Python exception (Py.E _) is raised if o is not a long. We have to_int o = Int64.to_int (to_int 64 o).
