17:18 Design #925: MachineInt or long for args which are indices (yet again): Postponing because there are too many other more pressing issues. Anyway the current code works adequately, so it is... John Abbott
11:51 Feature #813: Implement "elim" in CoCoALib: It would be nice to complete this before the next release! To this end, I have increased the priority... John Abbott
10:54 Feature #1277: Gaussian row reduction: NTL's doc shows just one fn *@gauss@* which accepts 2 args: matrix @M@ and an optional integer @w@ (default is number... John Abbott
10:44 Feature #1277: Gaussian row reduction: The request seems reasonable to me.
Not yet sure what the best design might be, but I suggest the following as a s... John Abbott
10:40 Feature #1277 (Closed): Gaussian row reduction: Julian Danner (Passau) would like CoCoA to offer matrix row reduction via gaussian elimination.
Discuss, design, i... John Abbott

21:05 Support #1276: Release 0.99650: List of principal changes made: *19th november 2019*
* NO LONGER C++03 compatible! We are moving towards C++14 (#89... John Abbott
21:03 Support #1276 (Closed): Release 0.99650: Description
Everything related to making a CoCoALib release:
* Redmine Roadmap: close or postpone issue
* ... John Abbott
18:38 Support #1039 (Resolved): Rename iroot?: I have changed the names into *@FloorRoot@* and *@IsExactFloorRoot@*.
Added *@iroot@* to @obsolescent.H/C@.
Test an... John Abbott
13:25 Support #1039: Rename iroot?: Even though GMP allows negative inputs to its @mpz_root@ function, I like the idea of limiting the number whose root ... John Abbott
13:57 Support #1263: Tidy CoCoALib test directory: I have noticed that there some tests which run quickly (_e.g._ less than 0.01s on my computer), but the compilation t... John Abbott

17:48 Feature #1267: Ideal equality: I'm very uneasy in doing an automatic choice: the "trick" might work out as a slow overhead in a long loop with many ... Anna Maria Bigatti
10:50 Support #1134: Organize better the documentation for CoCoALib: I am postponing this issue. Even though I think it is important, it is likely to need a lot of time; anyway, the doc... John Abbott

16:31 Feature #385: Design new errors using inheritance: This really the same as #743. John Abbott
16:26 Feature #743: Better errors: give supplementary info about the error: It would be nice to have a quiet moment to get this matter properly sorted out.
We really should try to deal with ... John Abbott
16:06 Design #581: C++14: MachineInt: I have modified the subject and description to refer to C++14 instead of C++11.
There is a summary of the integral... John Abbott
15:48 Feature #1218: 32-bit or 64-bit preprocessor macro?: We should check whether this still makes sense with C++14. I should also check on my little 32-bit machine...
John Abbott
15:46 Feature #1197: IsZeroDet: new fn: The idea is simple: compute the det modulo various primes, and if any is non-zero then we know the non-modular det is... John Abbott
12:30 Feature #1267: Ideal equality: A similar trick could be used for ideal membership: if @x@ is not in @I+J@ then it is certainly not in @I@.
John Abbott

21:31 Feature #658: Indets actually in a poly (or vector or matrix): It seems that there is already an impl in @SparsePolyOps-RingElem@.
There is no doc, no test. Also not exported t... John Abbott
15:16 Feature #1267 (In Progress): Ideal equality: Long sent me one example which wanted to test if a large ideal (in a ring with 36 indets) contained 1. He actually d... John Abbott
15:07 Feature #1269 (New): Ideal Ops: sort-cuts for trivial args?: A colleague here in Passau was disappointed that @intersection(ideal(1), J)@ was taking a long time, even though the ... John Abbott
15:00 Design #1255: Ideals with trivial GBasis: Generators which are monomials are also a special case.
Then one could imagine a more complicated "mixed" situatio... John Abbott
