- I have now updated the .C files too. Everything compiles and runs.
It is possible that I have missed some 0 (that w...

- 18:53 Design #1257 (In Progress): C++14: use nullptr
- I have done the header files. There may still be one or zeroes which escaped me (but I hope not). Next are the .C f...
- 11:24 Design #1257 (Closed): C++14: use nullptr
- From C++11 there is the constant *@nullptr@* for the null pointer.
Update our (C++) code to use it!
- 14:33 Support #1161: Split NumTheory.C into several smaller files
- Current state:
* *@NumTheory.C@*
* *@NumTheory-ContFrac.C@*
* *@NumTheory-CoprimeFactorBasis.C@*
* *@NumTheory-pr... - 14:10 Feature #1227: exgcd; solve Bezout equation
- I prefer to defer this question until later, until when we have decided what exactly @exgcd@ should do (and whether i...

- 17:59 Bug #1256: RingID: different values in test-output on different platforms
- Anna uses @clang@ on MacOS, while I use @g++@ on Linux.
We get different outputs for @test-output@: its seems that t... - 17:56 Bug #1256 (Closed): RingID: different values in test-output on different platforms
- In @test-output@ Anna and I get different outputs (due to different RingIDs) because we use different platforms.
I... - 17:31 Bug #1250: SEGV: CoCoALib with Normaliz in multithreading
- I have changed the @configure@ script so that it prints out a clearer summary.
I have changed the @Makefile@ so that...

- 16:34 Bug #1248: MinPolyQuot: guaranteed and ideal without GBasis
- Fixed.
Now, *guaranteed* computes GBasis if missing, so result is guaranteed.
Testing.
