BigInt

BigInt utilities with parsing, formatting and arithmetic

API

Overview​

The BigInt module provides utilities for working with JavaScript's native bigint type, including parsing, formatting, and arithmetic operations.

Creating BigInt values​

import { BigInt } from '@w5s/num';

// From a literal
const value = 42n;

// From a number
const fromNumber = BigInt.fromNumber(42);

// From Int
const fromInt = BigInt.fromInt(Int(42));

// Parsing from string
const parsed = BigInt.parse('123n'); // Option<bigint>

Arithmetic Operations​

BigInt supports arithmetic operations using bracket notation:

import { BigInt } from '@w5s/num';

const a = 10n;
const b = 3n;

// Addition
BigInt['+'](a, b); // 13n

// Subtraction
BigInt['-'](a, b); // 7n

// Multiplication
BigInt['*'](a, b); // 30n

Comparison​

import { BigInt } from '@w5s/num';

const a = 10n;
const b = 20n;

BigInt['<'](a, b);  // true
BigInt['>'](a, b);  // false
BigInt['=='](a, b); // false

Formatting​

import { BigInt } from '@w5s/num';

const value = 1234n;
BigInt.format(value); // '1234'
BigInt.format(value, { radix: 16 }); // '4d2'
