- 16:47 CoCoALib Feature #289 (New): PrimeField -- new fn?
- Is it worth adding a new fn *@PrimeField@*?
@PrimeField(0)@ gives @RingQQ()@
@PrimeField(p)@ gives @NewZmod(p)@

- 19:10 CoCoALib Feature #283: Rational approximation
- Added tests for various functions related to continued fractions. As a consequence, I found another bug (and fixed it).
- 16:06 CoCoA-5 Bug #287: --fullCoCoALibError prints too much (Try/UponError)
- Here is a simplistic solution: print all the "stack backtrace" information to a @string@. If the error is caught som...
- 12:00 CoCoA-5 Bug #287: --fullCoCoALibError prints too much (Try/UponError)
- It seems difficult to do because the error is actually dealt with by a proper C++ *try*, whereas printing (the error ...
- 11:21 CoCoA-5 Bug #287 (New): --fullCoCoALibError prints too much (Try/UponError)
- When using the flag *--fullCoCoALibError* CoCoA-5 prints the full CoCoALib error message.
It does so even inside t... - 15:52 Support #266 (In Progress): Compilation on M$Windows: cygwin
- I have added a new file *@INSTALL-cygwin@* in the CoCoA root directory; it contains a summary of various hints for pr...

- I describe here an easy way to check a list of tests (from @CoCoA-5/tests/anna.cocoa5@):...
- 10:43 CoCoA-5 Feature #101: rethrow in Try .. UponError .. EndTry
- What about this?
(note that, as said above, all other error information is lost :-( )...

- 18:52 CoCoA-5 Support #286 (Closed): How to test (automatically) a user defined CoCoA function
- When developing and changing a cocoa function it is useful to repeatedly run some tests.
Explain how to do this easily. - 18:34 CoCoALib Feature #283 (Feedback): Rational approximation
- JAA has changed the names (as agreed in point 2). Also changed doc.
Fixed a bug -- it gave the wrong answer for a...

- 16:12 CoCoA-5 Feature #273: Package for Polynomial Algebra Homomorphisms
- Giulia has finished the implementations for the easy case (polynomial algebras). There was some discussion of *@IsIn...
- 15:30 CoCoA-5 Feature #101: rethrow in Try .. UponError .. EndTry
- What is the correct way to write a CoCoA-5 test which checks that a certain call produces the expected error? It sho...

- 16:24 CoCoALib Support #285 (Closed): Notes for adding/removing files from documentation
- When adding or removing files from *CoCoALib-0.99NN/doc/txt* there are a few operations to do in *@doc/aux-txt2tags@*...
- 16:16 CoCoA-5 Feature #273: Package for Polynomial Algebra Homomorphisms
- Giulia showed her restructured code: generally very good, just a few minor criticisms were made.
For next time, she ...

- 16:56 CoCoA-5 Feature #284 (Closed): BuiltInFunctions: more flexible typing in one-line function declaration
- In file *BuiltInOneLiners* there are many function wonderfully declared in one line.
Unfortunately sometimes we need... - 15:46 CoCoALib Feature #283 (In Progress): Rational approximation
- JAA has implemented the fn in CoCoALib, and also make it available in CoCoA-5.
It remains only to decide the name(s),... - 15:31 CoCoALib Feature #283: Rational approximation
- Proposals for the name of the function:...
- 14:58 CoCoALib Feature #283: Rational approximation
- JAA proposes a function *@SimplestRationalInInterval@* which makes publicly accessible a feature already used interna...
- 14:55 CoCoALib Feature #283 (Closed): Rational approximation
- Add a new function which computes a good rational approximation within a specified *absolute* error. Laura needs thi...
- 14:55 CoCoALib Feature #150 (In Progress): RingOf rather than owner? (and than AmbientRing, ...)
- There are other cases: now I'm working on a (private) file with *GBEnv* and the function to get it form an object is ...

- 18:22 CoCoALib Feature #84: Names for random streams
- AMB will unify the documentation files -- and update the names of the random sequence classes!
JAA will unify the co... - 12:02 CoCoALib Feature #84: Names for random streams
- Approved the idea of *unifying the sources* after verbal discussion.
The best unified name seems to be *@random@*. - 11:57 CoCoALib Feature #84: Names for random streams
- Discussion via Skype:
instead of *sample* use *NextValue* to access a new element from a *RandomStream..* - 11:27 CoCoALib Feature #84: Names for random streams
- Following Alessandra Caleo's criticisms (see issue #75), we have modified the documentation and examples to make them...
- 12:14 CoCoALib Feature #282 (New): Global setting: to use IsProbPrime in place of IsPrime
- An idea: since *@IsPrime@* can be extremely slow for larger inputs, and since *@IsProbPrime@* is normally extremely r...

- 15:31 CoCoALib Feature #281 (New): Store unique copy of FF(p) in GlobalManager
- Now calling *ZZ/(7)* twice produces two different rings.
Maybe that should be stored into GlobalManager.
