Fortran has OO features these days. It is nice. I am kind of dumb and old-school so I wrote a bunch of code using macros to handle multiple precisions. If I could go back in time, I’d definitely just use object oriented code. In either case, though, “we can try a mixed precision implementation, I automatically generated single precision” is an incredibly liberating thing to be able to say as a computational scientist!
