I did and it did not seem to work. I ended up doing the following.
Verbose, isn't it?
If I do d=PyFloat_AsDouble(oDiscount); in the third "if", I get an
error. Maybe I missed something obvious.


		if(oDiscount==Py_None)
		{
		}
		else if(PyFloat_Check(oDiscount))
		{
			d=PyFloat_AsDouble(oDiscount);
		}
		else if(PyNumber_Check(oDiscount))
		{
			PyObject *pf=PyNumber_Float(oDiscount);
			if(pfDiscount)
			{
				d=PyFloat_AsDouble(pfDiscount);
			         Py_DECREF(pfDiscount);
			}
		}
		else ...
