@yzobus: can you please indicate the version of `nalgebra` you're using? Is it the latest one?
I agree with @Ralith here. @sebcrozet would you be willing to yank and publish a new minor version whenever you are able to find the time?
I am not able to look into this now, but would you please be willing to provide the exact code you're using, to make sure we can reproduce it when...
Just want to add that if you actually want this operation to reliably give you the correct result, you probably want to take a look at [Shewchuk's Robust Predicates](https://www.cs.cmu.edu/~quake/robust.html). Perhaps...
Thanks for your investigation @JulianKnodt! Perhaps to settle the matter; would someone be willing to compute the determinant with exact arithmetic? Perhaps some symbolic toolkit like Maple/Mathematica is able to...
I think in Mathematica/Maple, all you might have to do is to replace e.g. `98.1` with `981/10`. IIRC, these software packages will otherwise interpret decimal numbers as floating-point. There might...
@redxaxder: hah, I didn't actually look at the matrix itself - indeed it has redundant rows. That certainly settles it. Thanks! I don't think there's something inherently wrong here with...
Hmm I think this is probably just a brittle/flaky test, (un)fortunately. We should improve these but it's not easy, because without formal bounds on possible errors it's difficult to choose...
@sarah-ek: I'd love to hear your thoughts on a possible integration. Do you think a plan like what I've outlined makes sense? Do you foresee any problems, or can you...
Thanks for your input @tbetcke, really appreciate it! What is the rationale for having the intermediate `LinAlg` trait instead of, say, an `SVD` trait directly on the matrix? It's not...
