I understand that it is not following the rule of "converting the receiver to a float", but I would say that it follows the "principle of least surprise". Of course it is not possible to convert an Array to a Float in any meaningful way, so to convert each element into a Float is the behaviour I am expecting. Well... that's my thinking anyway. Fredrik
