ka VS mathjs

I wrote a command line calculator tool in ~1400 lines of Python and wanted to share it with you folks! It's called ka. You can run one-off commands like ka '1+1', or you can start an interpreter loop:

I actually started working on a CLI calculator a few days ago that sounds exactly like what you're looking for (it's for my own use): https://github.com/Kevinpgalligan/ka

So far it just has variables and basic arithmetic. Other features on my roadmap: rational numbers, numbers getting simplified to the simplest type in the hierarchy that can represent them (so 4/2=2 but 4/3=4/3 until you coerce it to a float), units (and conversions), and lazy/smart combinatorics.

What do you imagine the timezone DB would look like? I'd love to hear your ideas!

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.
