13:51 Bug #905: txt2tags: double quotes wrong in LaTeX: This is still a problem. It would be nice to fix it before a deadline on 29th Sept!
I am also not convinced by th... John Abbott
11:29 Bug #1310 (Feedback): RealRoots: gives odd number of roots for deg 6 irred poly: I have found a bug, and fixed it! It produces reasonable answers on the two tests mentioned above:... John Abbott
10:30 Bug #1310: RealRoots: gives odd number of roots for deg 6 irred poly: I now have a simpler failing example:... John Abbott

17:32 Bug #1310 (In Progress): RealRoots: gives odd number of roots for deg 6 irred poly: There appear to be two real roots: approx -4.00095 and 1.05
@RootBound(f)@ gives about 2.95; *this is wrong!* John Abbott
13:53 Bug #1310 (Closed): RealRoots: gives odd number of roots for deg 6 irred poly: The following looks to be wrong:... John Abbott
12:26 Design #1309: SmoothFactor: allow limit = 1?: I have just changed the code to allow limit=1. All tests and examples pass (which suggests that the tests were not v... John Abbott
11:58 Design #1309: SmoothFactor: allow limit = 1?: There are two separate impls for @SmoothFactor@ (one for @MachineInt@ and one for @BigInt@). One allowed the limit 1... John Abbott
11:41 Design #1309 (In Progress): SmoothFactor: allow limit = 1?: The original reason for imposing the limit was to help users detect "obviously silly" function calls. Now I think th... John Abbott
11:36 Design #1309 (Closed): SmoothFactor: allow limit = 1?: The @SmoothFactor@ function tries to factorize integers by dividing by all primes up to a specified limit.
Current... John Abbott

16:29 Bug #1308: test-GFan1 fails: How much backward compatibility should be maintained? It might be too tricky; perhaps we should just require that us... John Abbott

16:47 Feature #1306: exgcd over integers (ZZ): Name *@extgcd@*?
I prefer with the *'t'*
Anna Maria Bigatti
16:12 Feature #1306: exgcd over integers (ZZ): The cofactors are defined only modulo the lattice of "syzygies" (kernel of the row matrix); the hope is that the vect... John Abbott
16:08 Feature #1306 (In Progress): exgcd over integers (ZZ): Implement a general extended gcd over the integers.
The idea is that the cofactors should be reasonably small.
Pr... John Abbott

14:55 Feature #1227: exgcd; solve Bezout equation: An exgcd function would be very useful.
It is used in computing the Hermite normal form (#1304) and in computing Gr... Florian Walsh
