Hmm, not for me: In [56]: min(int16, int32) Out[56]: <type 'numpy.int16'> In [57]: max(int16, int32) Out[57]: <type 'numpy.int32'> On the other hand, even though dtype=int gives you an int32 array this does not work as expected: In [59]: min(int16, int) Out[59]: <type 'int'> Well I guess that shows how fragile using min/max is. And I don't think there's a way to make it always work because there are types that are not simply bigger/smaller but of a different kind. Cheers, Ralf
