    This was such a great read. I thought I mostly understood the problems with floating point maths but I learned a whole bunch of practical tips and real-world problems to look out for here.

      Another great explainer is this one by Bartosz Ciechanowski.

        This got me interested in reading the actual IEEE 754 spec, which is available for $100 on the ieee website. Does anyone know how I can obtain a copy for free? I had originally thought it was an open standards body but I guess not….

          I think “open” in this case means anyone with access to the documentation can make use of it without having to worry about copyright, etc. Most standards bodies charge money for the actual documents, which do require qualified people to put together.

          For a research library or even a small corporation, $100 is nothing.
