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

Use strings. For PHP specifically, the Brick/Math library.

How are you handling your money?
In Java and Ruby, BigDecimal is an inbuilt class that can be used. For PHP, you can checkout the Brick Math Library Basically, just find the arbitrary-precision Decimal type/Class/Library in your choice of language. Got another approach, please do let me know in comment section.

What are the latest thoughts on storing and working with very large and very small financial transactions?
I decided to use https://github.com/brick/math and store the amount as a string in the database. My project use NANO, so that's 30 decimal points to keep. Number type column is not the choice at all.

Vote for enums in PHP 8.1 has started — looking good so far!
There are many use cases where enums don't need to be backed by a scalar. I'm thinking of brick/math's RoundingMode for example: you use these in code, but never store/serialize them really.

(int) (round(19.33, 2) * 100) = 1932 - can someone please explain this to me?
Besides, using an arbitrary-precision library gives you an unlimited number of digits, and, in the case of brick/math, many more rounding modes to choose from. And predictable ones.
