Hi! Thanks for the amazing work on Catch2! > But I agree, there should be a way to switch to std::scientific. Is there any progress related to this? Thanks

Thanks for the improvement @hokb and @thijssteel! Should I write a PR with the modifications or are you willing to do that, @hokb?

Sure! It will be good to have this information well documented. To begin with, I spent some time tracking (maybe) all divisions in the files `LAPACK/SRC/z*.f` (COMPLEX*16 algorithms) of the...

@hokb, could you reproduce the overflow issues you mentioned in https://github.com/Reference-LAPACK/lapack/issues/575#issuecomment-855880000 with GCC using SSE flags? Can you help me with that?

I don't use windows, but I do have it here. I will start by testing LAPACK with ifort on my Ubuntu and see what happens. Enjoy the holiday!

I am coming back to this issue. Sorry for the delay. @hokb, did you try to compile/test with ifort using the flag '-xSSE2' ? Using the godbolt website, I noticed...

Hi @hokb, I think I can reproduce some precision issues for complex data. I tried ifort (IFORT) 2021.3.0 20210609 on my Ubuntu 18.04.5 LTS with the flags `-mno-x87 -complex-limited-range`. After...
