I think I should not have switched the linear algebra for matrices over ZZ (that was just a mistake, unfortunately, there were no tests of this behavior), possibly over QQ...

The 'solve' function, as implemented, is not designed to work over ZZ. There are two workarounds: 1. promote all matrices to QQ, solve there (as done above) 2. Use //:...

I am changing the code so that many linear algebra operations which involve LU decomposition, are not defined over ZZ. The code was incorrectly calling routines meant only for fields....

We also plan on doing this for the `Complexes` package, for the 1.17 release.

maybe there should be a type: FactoredRingElement, or FactoredFraction. Multiplication is easy, inverse too, addition would take out the common parts and add the rest, maybe there should be a...

I am too (in favor of changing it so it isn't surprising). However, it is a bit larger change, in that we have to make sure it is compatible with...

How are running the package tests handled on github?

Doug, yes, this appears to fix the problem. Thanks! I will add those, and see if any others are needed too. > On Sep 5, 2024, at 3:46 PM, Doug...
