* py/obj: Make mp_obj_get_complex_maybe call mp_obj_get_float_maybe first.Damien George2022-07-25
| | | | | | | | | | | | | | | | | | This commit simplifies mp_obj_get_complex_maybe() by first calling mp_obj_get_float_maybe() to handle the cases corresponding to floats. Only if that fails does it attempt to extra a full complex number. This reduces code size and also means that mp_obj_get_complex_maybe() now supports user-defined classes defining __float__; in particular this allows user-defined classes to be used as arguments to cmath-module function. Furthermore, complex_make_new() can now be simplified to directly call mp_obj_get_complex(), instead of mp_obj_get_complex_maybe() followed by mp_obj_get_float(). This also improves error messages from complex with an invalid argument, it now raises "can't convert <type> to complex" rather than "can't convert <type> to float".
