# super-number
[](https://www.npmjs.org/package/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
```sh
# Using npm
npm install --save super-number
```
### Usage
```js
const Ints = require('super-number');
// Syntax : Ints(array_of_integers).findNearestInteger(integer)
Ints([-5, -2, 0, 1, 5]).findNearestInteger(0); // expected output: 1
Ints([-5, -2, 0, 1, 5]).findNearestInteger(1); // expected output: 0
Ints([-5, -2, 0, 1, 5]).findNearestInteger(5); // expected output: 1
Ints([0, 1, 2, 5, 6]).findNearestInteger(5); // expected output: 6
Ints([-1, 0, 1]).findNearestInteger(0); // expected output: 1
Ints([-5, -2, 0, 1, 5]).findNearestInteger(-2); // expected output: 0
Ints([-5, -2, 0, 1, 5]).findNearestInteger(-5); // expected output: -2
Ints([-5, -4, -2, 0]).findNearestInteger(-2); // expected output: 0
