    I had never heard of this site. Now I am sad. It seems useful.

    It looks like only the English version is shutting down. The Japanese version seems to be going strong: https://keisan.casio.jp/

    Can someone explain what this is/was?

    If you want a self-hosted replacement for Keisan I strongly suggest looking at Qalculate! https://qalculate.github.io/

    Qalculate even looks up relevant facts online such as when used for real time currency conversion rates, e.g. 1000 JPY/USD

    (Self promotion) if people like the Casio style calculators, my app is heavily influenced by Casio’s scientific calculators. The editor works almost exactly like theirs, but it has a modern keyboard that’s optimised for touch screens. The rendering uses the LaTeX font too

    As well, you get a few dedicated modes, like unit conversion, date calculations etc.

    The high precision calculator was a true gem. I have used it a few times when I needed more precision than the 64bit that Javascript gives me. Is there an alternative somewhere?

    Seems like someone would have made a self-hosted clone of this on github by now.

    I loved the high precision calculator and used it occasionally. Sad to see it going.

    This is something I would love to see open sourced but I know that’s not going to happen.

    Site looks pretty nice. Too bad I just heard of it. I guess no easy way to archive this. This is my biggest grip with all that followed straight HTML.

    No, only the english part of the website is closing.

    Keisan means calculate. I've been to the site on occasion but I'm pretty sure I won't be missing much.
