Front-End Dilemmas: Tackling Precision Problems in JavaScript with Decimal.js
Desperate for a solution, I stumbled upon Decimal.js, a JavaScript library that provides arbitrary-precision decimal arithmetic. I was intrigued, so I decided to give it a try.

Rant - Javascript should be able to do simple f**king math by now
I too wish JS had a dedicated Decimal Type, but there is plenty of 3rd party libraries available like decimal.js

The Last Breaking Change | JSON Schema Blog
For your particular example though, if we keep in mind that the input data to be validated is JSON-serializable, only a string could possibly accommodate the precision expected of a decimal from among the JSON-serializable JS primitives. You could use one or more regex patterns to describe the allowable permutations. The resultant schema would be cross-platform since it doesn't use custom keywords - nice! You can also use unions if you want to say that integers, NaN, and Infinity are also allowed per the docs there.

Javascript precision with significant zeros
i've used Decimal.js to account for floating point issues in JS before. maybe this will help? I realize its not native and is a 3rd party lib - but its intent is to handle floating point issues and precision. That kinds sounds like the tree you're barking up right now. maybe it will help.

[AskJS] Are there numeric textbox widgets with built-in support for big numbers like decimal.js?
I'm working on a project where users will enter numbers like 9,999,999,999.99999 (up to 15 digits, up to 5 of them decimal) and we are having a problem with Numbers losing precision beyond certain number of digits (a typical issue for IEEE Standard 754 Floating Point Numbers, the 0.1 + 0.2 problem). I've solved this problem in a few projects before with the help of decimal.js or bignumber,js . In those cases, we kept user-input as strings and used a few custom-made numeric textbox widgets to accommodate this. Unfortunately, those widgets were proprietary... Now I need one again, but can't find anything. Do they exist?

Show HN: I made a web-based notepad with a built in unit calculator
Looks good! I love the idea of the embedded calculator
I noticed that it doesn't handle remainder/modulo (%) equations:
"10 % 2" results in: "Left hand side of addition cannot be a percentage."
It does look like decimal.js can handle that: https://mikemcl.github.io/decimal.js/#mod

Notepad Calculator
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.

Show HN: I made a web-based notepad with a built in unit calculator
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!
