Rewrite Number.prototype.toFixed to make it consistent across any environement and add more precision

Number.prototype.toFixed() rewrite

Description

As we know, Number.prototype.toFixed() has many problems due to precision.

For example, in NodeJS 8.11.3

(5.395).toFixed(2); // 5.39
-(5.395).toFixed(2); // -5.39
(1.395).toFixed(2); // 1.40
-(1.395).toFixed(2); // -1.4

and in IE9

(5.395).toFixed(2); // 5.40
-(5.395).toFixed(2); // -5.4
(1.395).toFixed(2); // 1.40
-(1.395).toFixed(2); // -1.4

This lib aims to make it consistent across any environment,

and above test result will be

(5.395).toFixed(2); // 5.40
-(5.395).toFixed(2); // -5.4
(1.395).toFixed(2); // 1.40
-(1.395).toFixed(2); // -1.40

How to use

Introduce it before your code

for example:

require('index');
// or
import './index.js';

// other codes
