- 16:30 Feature #627: Gaussian integer and rationals ZZi, QQi
- Recalling that every ring (except @RingZZ@) in CoCoALib has a @BaseRing@ and an "extension type". What should the @B...
- 11:40 Feature #627: Gaussian integer and rationals ZZi, QQi
- What should be the internal representation of an element of @QQ[i]@?
# a pair of @BigRat@ values (real and imag part...

- 18:16 Feature #628 (New): Complex twin-floats
- Ulrich would like to compute with (approximations to) complex numbers.
Can twin-floats be extended to complexes? ... - 18:15 Feature #627 (New): Gaussian integer and rationals ZZi, QQi
- Ulrich would like to have an easy way to compute with (approximations to) complex numbers.
Currently, it is possib...

- 13:44 Design #620: Redesign CRTMill
- Maybe the @vector@ version needs a little more thought.
In a deterministic algorithm, where we lift to an _a prior... - 13:26 Feature #625: NumTheory: sieve of Eratosthenes
- I have now checked in the code.

- 23:59 Feature #625: NumTheory: sieve of Eratosthenes
- Added maintainer doc, test (seems its was needed), and example (a bit difficult).
- 23:20 Feature #625 (Feedback): NumTheory: sieve of Eratosthenes
- Implemented, and added some doc.
Still need to do: maintainer doc, test, example.
- 23:19 Feature #625 (Closed): NumTheory: sieve of Eratosthenes
- In an example I needed a table like the Sieve of Eratosthenes. So I've implemented it, and added it to CoCoALib.

- 16:55 Design #620: Redesign CRTMill
- I have had a quick look at documentation for NTL and FLINT.
NTL has a very simple interface (like the existing one f... - 16:53 Support #624 (New): Wikipedia
- Improve the Wikipedia entry about CoCoA.
- 11:14 Feature #623 (Closed): Inverse of a matrix over ZZ
- Inverse of a matrix over QQ works fine.
Fix code so that it works for invertible matrices over ZZ.
(I have a big ex...

- 15:59 Design #620: Redesign CRTMill
- I expect the main case of adding residue-modulus pairs is when both are machine @long@ values, and we could reasonabl...
- 15:40 Design #620 (In Progress): Redesign CRTMill
- I envisage two types of use of a @CRTMill@:
# keep adding residue-modulus pairs until the combined modulus exceeds an... - 12:47 Design #620 (In Progress): Redesign CRTMill
- I have some ideas for alternative implementations of @CRTMill@, but they do not fit well with the current user interf...
- 12:37 Design #619: Modulus (for CRTMill) ambiguous
- An obvious "solution" is to put @using CoCoA::modulus@ somewhere inside the function which calls it. Just about acce...
