That depends on what the bounds on the error in that number are. If it's -2.5e-9 +- 1e-3 then it can very well be an approximation to 0 (which we know it is). It's the accuracy of the approximation that matters--not its size. -- You received this message because you are subscribed to the Google Groups "sage-devel" group.
