10:27 Feature #1644 (In Progress): Allow user to choose whether to print finite field elems as symm residues or non-neg residue

Anna suggests these names: *@AsINT_Symm@* and *@AsINT_NonNeg@* (because @AsINT_LeastNonNeg@ is too long)
The idea i... John Abbott

10:12 Feature #1648 (New): ApproxSolve and RationalSolve take different input

ApproxSolve expects an ideal (0-dim) and RationalSolve a list of polynnomials.
Choose which one we want, and modify ... Anna Maria Bigatti

10:10 Bug #1640 (Closed): MinSubsetOfGens does not find min subset

We had effectively already taken into account the comment 5 above.
Anna has just changed the code slightly to orde... John Abbott

20:32 Bug #1640: MinSubsetOfGens does not find min subset

Unfortunately I have lost the specific example (but I suppose a new one could easily be created).
I did notice the f... John Abbott

19:02 Feature #1644: Allow user to choose whether to print finite field elems as symm residues or non-neg residue

I have just given a demo to my students of using CRT to reconstruct a large integer value.
The demo happened to work... John Abbott

13:07 Feature #1644: Allow user to choose whether to print finite field elems as symm residues or non-neg residue

The current impl in @SmallFpImpl.H@ expects there to be a boolean data mem which says how to print (@LeastNonNeg@ or... John Abbott

12:58 Feature #1644: Allow user to choose whether to print finite field elems as symm residues or non-neg residue

JAA thinks that allowing the user to choose should not cause any problems: it is just a matter of printing.
Mmm, w... John Abbott

12:57 Feature #1644 (In Progress): Allow user to choose whether to print finite field elems as symm residues or non-neg residue

A student here asked how to make CoCoA-5 print elements of a finite field as the least non-neg residue class represen... John Abbott
