- 16:23 Feature #1488: BuiltIn Interreduce-Function
- Might it be useful to sort elements inside the interreduction loop according to a more "sophisticated" ordering: _e.g...
- 15:41 Feature #1488: BuiltIn Interreduce-Function
- I have now put my version of the impl in a new file *@SparsePolyOps-interreduce.C@* with corresponding header file.
... - 14:45 Feature #1488 (In Progress): BuiltIn Interreduce-Function
- Here is my revised version of the source code. It could surely be made faster, but this version is relatively simple...

- 14:06 Feature #1488 (Closed): BuiltIn Interreduce-Function
- The function @interreduce@ is implemented in CoCoA-5, and the implementation (@NotBuiltin.cpkg5@) can be translated i...

- 18:11 Feature #1485 (New): Simple syntax for making a quotient ring?
- The syntax *@R/I@* would be convenient and easy to read.
At the moment I do not see how it could be "dangerous" un... - 17:56 Feature #1485 (Resolved): Simple syntax for making a quotient ring?
- 17:47 Feature #1485 (New): Simple syntax for making a quotient ring?
- Should we allow the syntax *@R/I@* to mean the same as *@NewQuotientRing(R,I)@*?
Discuss, and maybe implement.
- 18:08 Bug #1484 (Resolved): ker bug (quotientinghom for R/ideal())
- There are two more suspect creations of ideals: line 325 and 347.
I have changed these too, but am less sure that wh... - 18:07 Bug #1484: ker bug (quotientinghom for R/ideal())
- I have blindly changed the code in @HomomorphismOps.C@.
The problem was in @MakeRichHom@ (and presumably an analogo... - 17:38 Bug #1484 (Closed): ker bug (quotientinghom for R/ideal())
- Bernhard Andraschko reports the following bug:...
- 13:10 Feature #1483 (Feedback): IsPowerOf2 for rationals
- Added new function *@IsPowrerOf2@* for @BigRat@. Gives @false@ if arg is not strictly positive.
Impl is simple rath... - 13:08 Feature #1483 (Closed): IsPowerOf2 for rationals
- Add new function *@IsPowerOf2@* for @BigRat@.
It already exists for @BigInt@.

- 14:56 Feature #1482: Extended rationals: PlusInfinity and MinusInfinity
- Maybe the simple approach is to create two new types: *@PlusInfinityType@* and *@MinusInfinityType@*. Then it should...
- 14:48 Feature #1482 (In Progress): Extended rationals: PlusInfinity and MinusInfinity
- The doc for GMP states fairly clearly that the rationals @1/0@ and @-1/0@ can be created, but that they may not be pa...
- 14:02 Feature #1482: Extended rationals: PlusInfinity and MinusInfinity
- Some notes:
* what type should these values have? *@BigRat@*? Or Maybe *@ExtendedBigRat@*?
* We'd probably need f... - 13:56 Feature #1482 (In Progress): Extended rationals: PlusInfinity and MinusInfinity
- Might we be interested in having representations of *@PlusInfinity@* and *@MinusInfinty@*?
This could be useful fo... - 14:34 Feature #1176: interval arithmetic
- There is a GNU package called MPRIA (multiple precision rational interval arithmetic). It is GPL v3.
It seems not t...

- 15:40 Support #1481: Release CoCoALib 0.99800
- Summary of main changes:
* *changed @BigRat@ ctors*: it is now possible to construct @BigRat@ directly from an integ... - 15:39 Support #1481 (Closed): Release CoCoALib 0.99800
- Everything related to making a CoCoALib release:
* Redmine Roadmap: close or postpone issue
* Redmine Release... - 13:47 Support #1196 (In Progress): Split MatrixOps
- For "other reasons" I have split off the code related to computing determinants: this code is now in *@MatrixOps-det....
