1) Is it worth investigating the reason for the difference?
No, but it is worth determining how bad the error is. In all cases, I would say that an error of less than 1 ulp is totally acceptable. If the error is 1 ulp or more for a basic function (like log) on a reasonable non-pathological input (like 3.0), I would consider that an upstream bug. Still, it would not necessarily be a problem for Sage if the error is a few ulp.
3) Or should the test just be updated to ignore the last couple digits of the result, and if so how (ellipses?)
The best way is to use # (rel|abs) tol in the doctest. -- You received this message because you are subscribed to the Google Groups "sage-devel" group.
