You should have been more precise then : "In my ideal world, when dividing a non zero value by a zero value, the result should be +Inf or -Inf according the the sign rules" On that point, you should also note that +0 and -0 are sometimes considered two different floating point numbers in Python :) -- http://mail.python.org/mailman/listinfo/python-list
