isitodd

Strongly-typed odd/even utilities for number and bigint.

Install

npm install isitodd

Usage

ESM:

import { isOdd, isEven } from 'isitodd'

isOdd(3) // true
isEven(4n) // true

CommonJS:

const { isOdd, isEven } = require('isitodd')

isOdd(-1) // true
isEven(0) // true

API

• isOdd(n: number | bigint): boolean
• isEven(n: number | bigint): boolean

Notes:

• number inputs must be finite integers (throws otherwise). bigint has no such restriction.
• Negative values are supported.
