yup, that does it, I hadn't found that, as I was expecting a more OO 
way, i.e. as a method of the dtype.

Also, I need to know in advance if it's a int or a float, but I suppose 
you can't really do much without knowing that anyway.

Actually, I'm a bit confused about dtypes from an OO design perspective 
anyway. I note that the dtypes seem to have all (most?) of the methods 
of ndarrays (or placeholders, anyway), which I don't quite get.

oh well, I've found what I need, thanks.
