21:30 CoCoALib Design #1768: Limit indentation in verbose mesgs?

*Anna* will test the updated code shortly (I hope)

21:29 CoCoALib Slug #1769 (Feedback): FixedDivisor is sometimes surprisingly slow

I regard this as fixed: the remaining work is in issue #1770 John Abbott

21:16 CoCoALib Design #1771 (Resolved): Hadamard bound: field names

During a telephone discussion with Anna, we decided it makes sense to change the field names. Of course, this is not... John Abbott

21:39 CoCoA-5 Support #1636: Missing/Incomplete manual entries

Here is the result of my first sweep:
* @fgrep "No exact match" ...@ [44 lines]
* @fgrep "No matches" ...@ [336... John Abbott

21:34 CoCoA-5 Support #1636 (In Progress): Missing/Incomplete manual entries

Here is a start to finding which functions need manual entries but don't have them.
Below is some CoCoA-5 code whi... John Abbott

22:29 CoCoA-5 Feature #980 (In Progress): CoeffSize: function to measure the size of coeffs in a poly

JAA notes that @FloorLog2@ is faster than @FloorLog10@ -- a quick check suggest at least 100 times faster.
Also @Flo... John Abbott

22:17 CoCoA-5 Design #1772: Continued fraction: arg type RAT or RAT/INT?

Possible options:
* disable the auto conversion from @RAT@ to @INT@ -- JAA doubts that this is wise (it could cause ... John Abbott

22:12 CoCoA-5 Design #1772 (New): Continued fraction: arg type RAT or RAT/INT?

Currently the continued fraction functions expect an arg of type @RAT@.
This cause a problem in one program I wrote ... John Abbott

19:41 CoCoALib Slug #1769 (Resolved): FixedDivisor is sometimes surprisingly slow

I have changed the code to use the new prototype evaluation code (see issue #1770), and it is now usefully faster :-)... John Abbott

12:12 CoCoALib Design #1771 (Closed): Hadamard bound: field names

CoCoALib and CoCoA-5 offer a function to compute Hadamard's bound (for determinants).
The function actually compute ... John Abbott

23:17 CoCoALib Feature #1770 (In Progress): Evaluate polynomial function/class

I made a quick prototype, and used it in a revised version of @FixedDivisor@ (in @PolyRing.C@).
It made the code abo... John Abbott

23:15 CoCoALib Feature #1770 (Closed): Evaluate polynomial function/class

Create a class(?) to make it easier to evaluate polynomials.
A first prototype is in *@SparsePolyOps-cyclotomic@* (... John Abbott

@FixedDivisor@ can sometimes be unexpectedly slow.... John Abbott

22:10 CoCoALib Design #1768 (Resolved): Limit indentation in verbose mesgs?

I have checked in a first version (but not actually tested it...) John Abbott

10:05 CoCoALib Design #1768 (In Progress): Limit indentation in verbose mesgs?

The point is whether we should impose a limit. I agree that 20 is probably too low. We can try with 100, and possib... John Abbott

19:34 CoCoALib Design #1768: Limit indentation in verbose mesgs?

I suggested a limit of 20 because that is not so much indentation, and I can imagine few genuine situations where we ... John Abbott

19:32 CoCoALib Design #1768 (Closed): Limit indentation in verbose mesgs?

I have an infinite recursion bug, and with verbosity active the indentation becomes rather large :-/
Should we impos... John Abbott
