Inspired by [Decimal rounding polyfill by MDN](https://developer.mozilla.org/en/docs/Web/JavaScript/Reference/Global_Objects/Math/round#Decimal_rounding).
|
||
|
|
|
||
|
|
__Installation__
|
||
|
|
|
||
|
|
Install using npm:
|
||
|
|
|
||
|
|
```bash
|
||
|
|
$ npm install round10
|
||
|
|
```
|
||
|
|
|
||
|
|
__Usage__
|
||
|
|
|
||
|
|
Use in your project:
|
||
|
|
|
||
|
|
```bash
|
||
|
|
$ npm install --save round10
|
||
|
|
```
|
||
|
|
|
||
|
|
and in your code:
|
||
|
|
|
||
|
|
```javascript
|
||
|
|
var round10 = require('round10').round10;
|
||
|
|
round10(55.55, -1); // 55.6
|
||
|
|
```
|
||
|
|
|
||
|
|
Optionally, you may use the polyfill which extends the global Math object:
|
||
|
|
|
||
|
|
```javascript
|
||
|
|
require('round10').polyfill();
|
||
|
|
Math.round10(55.55, -1); // 55.6
|
||
|
|
```
|
||
|
|
|
||
|
|
