Stars - the number of stars that a project has on GitHub. Growth - month over month growth in stars.
Activity is a relative number indicating how actively a project is being developed. Recent commits have higher weight than older ones.
For example, an activity of 9.0 indicates that a project is amongst the top 10% of the most actively developed projects that we are tracking.

Show HN: Heynote – A Dedicated Scratchpad for Developers
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.

Decoding Why 0.6 + 0.3 = 0.8999999999999999 in JS and How to Solve?
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.

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.

In the example provided, the name of the library is literally Decimal.js: https://mikemcl.github.io/decimal.js/

[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
