What even is a JSON number?

   1 250 1,465 2.0 CSS

   Floating Point Math Examples

   Although it would be good to move in the direction of using a BigDecimal equivalent by default when ingesting unknown data.

   If you would like to contribute Swift tests, I would be happy to take it! You can send a PR into this document, updating the data tables and adding a code sample at the end: https://github.com/bterlson/blog/blob/main/content/blog/what.... No need to test openapi-tools swift codegen unless you really want to!

4. json

   3 43 5,088 9.1 Rust

   Strongly typed JSON library for Rust (by serde-rs)

   

   Oh wow. So serde_json doesn't roundtrip floats by default, it uses some imprecise faster algorithm https://github.com/serde-rs/json/issues/707

   Good thing there's msgpack I guess.

5. zod

   4 357 36,049 9.0 TypeScript

   TypeScript-first schema validation with static type inference

   

   In JS, it's a good idea anyway to use some JSON parsing library instead of JSON.parse.

   With Zod, you can use z.bigint() parser. If you take the "parse any JSON" snippet https://zod.dev/?id=json-type and change z.number() to z.bigint(), it should do what you are looking for.
