||
|
|
|
||
|
|
```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) {
|
||
|
|
|
||
|
|
}
|
||
|
|
```
