There were also some problems with int to python conversion - assigning a PyLong to a KX_GameObject from python would raise an error - PyLong were coerced into floats when used with internal CValue arithmetic Changes... - PyLong is converted into CIntValue for coercing and assigning from python - CValue's generic GetNumber() function returns a double rather then a float. - Print an error when a PyType cant be coerced into a CValue Tested with python, expressions and property sensor.
