## Installation
```console
npm install num2fraction
```
## Usage
```js
var π = Math.PI
var n2f = require('num2fraction')
console.log(n2f(0)) // => 0
console.log(n2f(.2)) // => 1/5
console.log(n2f(1.1)) // => 11/10
console.log(n2f(1.2)) // => 6/5
console.log(n2f(1.3)) // => 13/10
console.log(n2f(1.4)) // => 7/5
console.log(n2f(1.5)) // => 3/2
console.log(n2f(2)) // => 2/1
console.log(n2f(2.1)) // => 21/10
console.log(n2f(3)) // => 3/1
console.log(n2f(2.555)) // => 511/200
console.log(n2f(8.36)) // => 209/25
console.log(n2f('3em')) // => 3/1
console.log(n2f('1.5px')) // => 3/2
console.log(n2f(7 / 9) // => 7/9
console.log(n2f(8 / 9) // => 8/9
console.log(n2f(512 / 999) // => 512/999
console.log(n2f((2 * π / 3) / π) // => 2/3
console.log(n2f((8 * 5) / (4 / 2)) // => 20/1
```
## Example
Opera [old versions](http://www.opera.com/docs/specs/presto28/css/o-vendor/) support the non-standard `-o-min-device-pixel-ratio` or `-o-max-device-pixel-ratio` in CSS media queries.
```css
@media
only screen and (-webkit-min-device-pixel-ratio: 2),
only screen and ( min--moz-device-pixel-ratio: 2),
only screen and ( -o-min-device-pixel-ratio: 2/1), /* Opera */
only screen and ( min-device-pixel-ratio: 2),
only screen and ( min-resolution: 192dpi), /* fallback */
only screen and ( min-resolution: 2dppx) {
}
```
