16:10 Feature #630 (Closed): Add graeffe function?: Add a new fn @graeffe@ which transforms a polynomial into one whose roots are the squares of the root of the original... John Abbott

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
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... John Abbott

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... John Abbott
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).
John Abbott
23:20 Feature #625 (Feedback): NumTheory: sieve of Eratosthenes: Implemented, and added some doc.
Still need to do: maintainer doc, test, example.

23:47 Design #620: Redesign CRTMill: It could be interesting to have a @vector@ version of @CRTMill@ which accepts vectors of residues along with a single... John Abbott

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
16:53 Support #624 (New): Wikipedia: Improve the Wikipedia entry about CoCoA. John Abbott
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... Anna Maria Bigatti
