[Numpy-discussion] Conversion float64->int bugged?

ke Python's 'float_int' or 'long_int' functions (see $PYTHON_SRC_DIR/Objects/floatobject.c, $PYTHON_SRC_DIR/Objects/longobject.c): if it doesn't fit in an int, return a long. For now (svn), it seems that numpy is always using PyInt_FromLong after an implici
