Alternatively, if boolean arrays are a much more compact memory footprint, then return two overflow arrays, one positive and one negative. Use case: X = ... something ... Y = ... something else ... Z, ovpos, ovneg = multiply_check_ov(X,Y) if ovpos.any(): np.iinfo(Z.dtype).max if ovneg.any(): # uh oh, something we didn't expect, so raise an error _______________________________________________ NumPy-Discussion mailing list -- numpy-discussion@python.org To unsubscribe send an email to numpy-discussion-le...@python.org https://mail.python.org/mailman3/lists/numpy-discussion.python.org/ Member address: arch...@mail-archive.com
