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.

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.

I'm too afraid to ask
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

Bloomberg invests in Node.js – Shouldn't you?
Bloomberg are currently sponsoring Igalia to work on adding native Decimal number support to JavaScript.

This is an active proposal and was last discussed in the September 2023 meeting.

Wasmer takes WebAssembly libraries mainstream with WAI
would it be possible, for example, to access the standard decimal library of C# or Python via Javascript, thus not having to wait for the TC39 spec / implementation? [1]

Speeding up the JavaScript ecosystem - one library at a time
There's a BigDecimal TC39 proposal to bring this kind of thing to the native language, but until then you have to choose between accuracy and performance.

Best way to deal with excessive decimal results in calculator
To solve the problem while JavaScript waits on its own BigDecimal API, you can use something like bignumber.js to perform your calculations.

How can i prove that 0.1 + 0.2 = 0.3 is there like a function or ANYTHING i can do to bypass this error which occurs in most programming languages

Integer Math in JavaScript
given the popularity of javascript, it's about time we had better native tools for dealing with numbers in general, but it seems like the discussion is very slow on this front. for instance, the decimal proposal is still at stage 1 [1]. and no, BigInt does not solve that.
