Under the proposed behavior, if the random number is 30000, then you *still* may have negative values, and if it's 50000, you get ValueError. No, I don't think the behavior you outlined is particularly nice, but (1) it's consistent with array addition elsewhere, at least in my mind, and (2) I don't think that sometimes getting a ValueError is a big improvement. Although I still prefer automatic upcasting, this discussion is really making me see the value of a nice, simple rule like in 1.5. :) Andrew _______________________________________________ NumPy-Discussion mailing list NumPy-Discussion@scipy.org http://mail.scipy.org/mailman/listinfo/numpy-discussion
