A various JavaScript utility library for performing arbitrary-precision arithmetics.

🚀 Packages

• @bignum/core
  • Arbitrary-precision decimal arithmetic with BigInt.
• @bignum/template
  • Write formulas with template literals.
• @bignum/template-light
  • Write formulas with template literals. (light version)

📖 Basic Examples

import { BigNum } from "@bignum/core";

// Perform exact calculations using the arbitrary-precision arithmetic with BigInt.
console.log(BigNum.valueOf(0.2).add(BigNum.valueOf(0.1)).toString()); // 0.3
console.log(0.2 + 0.1); // 0.30000000000000004

import { setupEngine } from "@bignum/template";

const f = setupEngine();
const num = 0.1;
const result = f`${num} + 0.1 * 2`;
console.log(result); // 0.3
