But I do! I'm looking for something that implements the multiply_check_ov(X,Y) and similar functionality for addition and subtraction, for large arrays; I don't know how to do that efficiently. (Or even correctly for 64-bit operands --- for 8/16/32 I suppose as a baseline I could do the math in 64-bit arithmetic and if the answer doesn't match, then use the sign bit of the 64-bit result for determining overflow.) _______________________________________________ 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
