Original bug ID: 7868 Reporter: skaller Assigned to:@gasche Status: resolved (set by @alainfrisch on 2018-10-26T13:30:36Z) Resolution: fixed Priority: normal Severity: minor Version: 4.07.1 Fixed in version: 4.08.0+dev/beta1/beta2 Category: documentation Monitored by:@nojb
Bug description
The docs say Set.diff is "set difference".
As I pointed out years ago (why isn't this fixed!!) there are TWO operations called set difference. Both should be provided IMHO but at least the one that is provided should be properly specified.
Is this (a) the symmetric difference, equal to the union with the intersection removed, OR is it (b) the asymmetric difference, the elements of the first set with those of the second which are in it removed?
Steps to reproduce
Just read the docs.
The text was updated successfully, but these errors were encountered:
I think that the "set difference" terminology is much more common than "asymmetric difference" (people referring to the "symmetric difference" always mention "symmetric" explicitly), and so there should be no risk of confusion. But I wouldn't be opposed to make things more explicit, if you or someone else want to propose a PR to improve the documentation.
