@types/big.js

What is @types/big.js?

@types/big.js provides TypeScript type definitions for the big.js library, which is used for arbitrary-precision decimal arithmetic in JavaScript.

What are @types/big.js's main functionalities?

Basic Arithmetic Operations

This feature allows you to perform basic arithmetic operations such as addition, subtraction, multiplication, and division with arbitrary precision.

const Big = require('big.js');
const a = new Big(0.1);
const b = new Big(0.2);
const sum = a.plus(b); // 0.3
const difference = a.minus(b); // -0.1
const product = a.times(b); // 0.02
const quotient = a.div(b); // 0.5

Comparison Operations

This feature allows you to compare two Big numbers using methods like eq (equal), gt (greater than), and lt (less than).

const Big = require('big.js');
const a = new Big(0.1);
const b = new Big(0.2);
const isEqual = a.eq(b); // false
const isGreaterThan = a.gt(b); // false
const isLessThan = a.lt(b); // true

Rounding

This feature allows you to round a Big number to a specified number of decimal places.

const Big = require('big.js');
const a = new Big(1.2345);
const rounded = a.round(2); // 1.23

Conversion to String

This feature allows you to convert a Big number to a string representation.

const Big = require('big.js');
const a = new Big(1.2345);
const str = a.toString(); // '1.2345'

Other packages similar to @types/big.js

decimal.js

decimal.js is another library for arbitrary-precision decimal arithmetic. It offers more features compared to big.js, such as support for complex mathematical functions and configuration options for precision and rounding.

bignumber.js

bignumber.js is a library for arbitrary-precision arithmetic with a focus on performance. It provides similar functionality to big.js but is optimized for speed and efficiency.

mathjs

mathjs is a comprehensive mathematics library that includes support for arbitrary-precision arithmetic along with a wide range of other mathematical functions and utilities. It is more feature-rich compared to big.js but also larger in size.
