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... John Abbott
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... John Abbott

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? ... John Abbott

13:26 Feature #625: NumTheory: sieve of Eratosthenes: I have now checked in the code.
John Abbott

23:59 Feature #625: NumTheory: sieve of Eratosthenes: Added maintainer doc, test (seems its was needed), and example (a bit difficult).
John Abbott
23:20 Feature #625 (Feedback): NumTheory: sieve of Eratosthenes: Implemented, and added some doc.
Still need to do: maintainer doc, test, example.
John Abbott
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... John Abbott

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... John Abbott
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... John Abbott
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... John Abbott
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... John Abbott

(keep up-to-date) Anna Maria Bigatti
15:25 Design #619: Modulus (for CRTMill) ambiguous: I do not understand why the compiler thinks that @modulus(crt)@ is ambiguous.
There is an STL template fn @modulus@,... John Abbott
15:22 Design #619 (Closed): Modulus (for CRTMill) ambiguous: The type @CRTMill@ has an associated function @modulus(const CRTMill&)@; however calling the function the obvious way... John Abbott
12:21 Feature #617: configure: check all libraries for compatibility: The advantage of a single test is that it is easier to manage and maintain.
