- 17:09 CoCoALib Bug #413: OrdvArith: use of a single buffer is NOT THREADSAFE
- JAA ha now implemented a partial fix to the problem: the new design should allow the multithreaded case to be handled...
- 17:02 CoCoALib Design #415 (Closed): Remove AsPolyRing etc?
- I'm fed up with having to make explicit "manual" casts from @ring@ to @PolyRing@ etc.
I've just fixed a line of co...

I like @Set... - 18:07 CoCoA-5 Feature #414: New fn to increase max recursion depth
- Candidates for the name of the new fn:
@SetMaxCallDepth@
@SetCallDepthLimit@
It is probably best not to call it ... - 17:59 CoCoA-5 Feature #414 (Closed): New fn to increase max recursion depth
- Add a new fn to allow the user to increase the max recursion depth (currently hardwired to 2000)
What should the f...

- 19:14 CoCoALib Bug #413 (Closed): OrdvArith: use of a single buffer is NOT THREADSAFE
- Fix @OrdvArith@ fns so that they are threadsafe; at the moment they use a single buffer (@myOrdvBuffer@ and @myExpvBu...

- 19:58 CoCoALib Feature #233: AsINT and AsRAT -- ConvertTo<BigInt> and ConvertTo<BigRat>
- An advantage of Anna's suggested names is that they are more compact than using the @ConvertTo@ template fn.
JAA s... - 19:51 CoCoALib Feature #342: Remove denominators: QQ[x] -> ZZ[x] (and PushBack(coeff, PP))
- @PushFront@ and @PushBack@ for PPs have already been implemented (no idea when), but they were not documented. I hav...

- I, too, favour proposal (1):
* it is far simpler to implement
* it is simple to understand the restriction
* it shoul... - 19:04 CoCoALib Feature #342: Remove denominators: QQ[x] -> ZZ[x] (and PushBack(coeff, PP))
- Dear Anna,
I agree that (1) is the better choice. Given that PushBack copies the exponent vector, I think it is th... - 18:50 CoCoALib Feature #342 (In Progress): Remove denominators: QQ[x] -> ZZ[x] (and PushBack(coeff, PP))

Meanwhile @IsZeroDivisor@ has been implemented a...
