Cast number type to BigDecimal TypeScript ( Angular)

Question

I need to send a BigDecimal value from my angular front-end part to the java back-end. I tried to find a valuable solution but it seems that TypeScript knows only number type.

Is there any way to declare/cast a BigDecimal attribute in my angular project?

private totalPrice: number;

Javascript doesn't type variables : it only knows strings and numbers. If you want a BigDecimal in your back-end, consider parsing it in Java once you receive it. — user4676340

After couple of libraries tried, big.js seems the best:

Install the library using the following command in root folder:

$ npm install --save big.js

Import:

import Big from 'big.js';

Use:

private totalPrice: any;
this.totalPrice = Big(number_value).toPrecision(2) --> (e.g. 15.00)

You can add the TypeScript definition too, according its docs: github.com/MikeMcl/big.js/#typescript
