My training was 35 years ago, I have no idea where to go look for this

Fortran programmers are formally trained (at
least I
was, there was a whole semester devoted to this) in accumulated errors.
You did a deep dive into how to code stuff so that the error was reduced
each time instead of increased. It has a lot to do with how floating
point works, it's not exact like integers are.
I was unaware that there's formal training to be had around this but
it's something I'd like to learn more about. Any recommendations on
materials? I don't mind diving into Fortran itself either.
