Double.js instead of big.js

[munrocket]

Consider double.js instead of big.js. Check how faster it is

Hi @munrocket and thank you for your suggestion.

Using a WASM library wouldn't be much faster for less complex calculations (as done with trading-signals) because of the overhead from WASM to JS communication.

When executing your performance benchmark, then it also shows me an error.

Yea WASM version is not fit to you, anyway even JS version is significantly faster. x10 or something.
You can check benchmark here.
I will update measurethat benchmark later, error related to declaration.

Hi @munrocket, I tried to use double.js today but when importing it I am receiving the following error:

Could not find a declaration file for module 'double.js'.

Do you plan to add TypeScript definitions in your library? https://www.npmjs.com/package/double.js

Hi, can you add .d.ts with ChatGTP/Claude and push it in /dist/double.js.d.ts ?

[bennycode]

I think it is much better if you generate it from your TypeScript source code: https://github.com/munrocket/double-js/blob/v0.4.1/src/double.ts

Not on computer, but I can press merge button. Ty.

Without first-class TypeScript support, the double.js lib isn't suitable for "trading-signals".

[munrocket]

It is already in Typescript.

It seems TS need some hint in package.json. That’s all.
