super-number

This is a tool that provides extra Integer or Number methods. It allows to perform some actions more easily with Intseger or only Number types which makes it simpler, more flexible, more practical and less effort.

Installation

# Using npm
npm install --save super-number

Usage

const Ints = require('super-number');

// Syntax : Ints(array_of_integers).findNearestInteger(integer)
