- I don't think we should allow other integer types, after all we want to discourage other integer types.
One think I ... - 11:52 Design #825: IsPositiveGrading -- really need 2 signatures?
- -- fixed test anna.cocoa5
-- updated CoCoA-5 manual
-- made suggestion for submat ;-)

- It was quite trivial to add the new fns. I have updated the doc too.
Should there be a specific test?
Should imp... - 18:16 Feature #836 (Closed): SmallFpImpl: export fns for a fixed convention

- 22:08 Bug #834 (In Progress): Fix test failures (after revising MatrixForOrdering)

IsPositiveOrd wants @rk(M) == NumRows(M)@.
This function is called when making a term ordering o... - 13:41 Bug #834: Fix test failures (after revising MatrixForOrdering)
- JAA believes the root cause is the check that a grading is strictly positive when weakly positive is sufficient.

But first some Gluehwein ;-) - 17:00 Feature #142: Improve threadsafety

- 16:48 Feature #835: Make Mario's new code threadsafe
- See the examples in issue #784; I think this should cover many cases.
- 14:03 Feature #835 (New): Make Mario's new code threadsafe
