Dear list,
I exported the C++ function `sin` both for real and complex numbers
(`float` and `complex` in python / `double` and `std::complex` in C++)
and I noticed that calling `sin(2.3)` gives `(0.7457052121767203-0j)`
so a complex number. Why is that? In which order does boost python
handle overloading of functions anyways?
More precisely I exported this function to python
>>> sin?
Type: function
Base Class: <type 'builtin_function_or_method'>
String Form: <Boost.Python.function object at 0x26358e0>
Namespace: Interactive
Docstring:
sin( (float)arg1) -> float :
C++ signature :
double sin(double)
sin( (complex)arg1) -> complex :
C++ signature :
std::complex<double> sin(std::complex<double>)
Notice in particular that the `float` version is above the `complex`
version, so if boost::python things this is ambiguous (I don't
condider this abiguous), but even if so I was kind of expecting him to
use the first exported function, not the second.
Any ideas?
-Holger
