numi VS mathjs

This looks fantastic. I will definitely give it a spin. I've been tracking what I call "computational scratchpad" apps for a while now but haven't found one that fits my environment/workflow yet. Maybe Heynote will. Here are some others that I've looked at:

* https://soulver.app Granddad of them all, Mac-only, proprietary, expensive

* https://numi.app Mac-only, proprietary, semi-expensive. Has a Github and claims to be MIT-licensed but I don't see how you could build a working application with what's in the repo.

* https://calca.io Windows- and Mac-only, proprietary, not expensive, nice docs.

* https://notepadcalculator.com Web-based, not open source, hosted but uses local storage. You can optionally create an account to sign in and have your notes saved in plaintext on his server.

* https://github.com/bbodi/notecalc3 Web-based, open source, self-hostable. But it seems to save your document in the URL string itself, which means the URL gets updated with almost every keystroke. Worth it for quick calculations and very small notes, I guess.

* https://numpad.io Web-based, hosted, not open source. Also stores entire doc in URL, but doesn't update the URL bar the whole time you're typing.

* https://numbr.dev/ Web-based, hosted. Has a Github but is not open source and the repo does not have all the bits needed to self-host it. Stores entire doc in URL.

* https://github.com/metakirby5/codi.vim Vim/NeoVim plugin that is less like a "smart notepad" and more like Jupyter but with results printed on the right side of the screen instead of in a cell below. Supports lots of programming languages.

Numi is an awesome little calculator app that supports currency conversion.

https://numi.app/ is a great calculator, you can define different values and reuse them multiple times in an easy way

Numi - calculator with a lot of functionality

Numi is a free alternative to Soulver.

The Math blocks are powered by Math.js (https://mathjs.org/).

math.js is a comprehensive JavaScript library that offers support for working with matrices and multidimensional arrays. It contains a huge array of mathematical functions in addition to array operations, making it suitable for a wide range of mathematical activities.

ii) Third-Party Libraries There are various libraries like math.js, decimal.js, big.js that solve the problem. Each library functions according to its documentation. This approach is comparatively better.

mathjs integration. Supports numbers, big numbers, complex numbers, fractions, units, strings, arrays, and matrices. Is compatible with JavaScript’s built-in Math library. Contains a flexible expression parser. Does symbolic computation. Comes with a large set of built-in functions and constants.

hey, this looks interesting. there is library, mathjs , that is providing pretty printing , which I'm looking for.

It's because it's not supported out of the box by the mathjs library I'm using: https://mathjs.org/

I agree that this would be nice.

Ha, yes, I was being nosy. It was quite easy to spot as it's the only XHR/Fetch request.

I was intrigued what you had used to build it, and if you had built your own solver (which you have), and what editor you used (Code Mirror) so went looking at the code. Interesting to see you left the source maps for production, made it easy for my sleuthing...

I experimented with a similar idea last year, but used ProseMirror/TipTap as the editor to enable rich text editing, and the MathJS (https://mathjs.org) solver. I also combined it with PouchDB and Yjs for offline editing and syncing between devices. Never finished it though, you have kept your nice and simple!

This is nice but I believe something much better can be achieved using JavaScript, in particular math.js.

I also found this math input library: http://mathquill.com/ , and https://mathjs.org/ seems to contain code for solving math problems.

What about math.js? It has an expression parser that looks pretty nice.
