Parse numerator and denominator from a string.

[![npm install parse-fraction](https://nodei.co/npm/parse-fraction.png?mini=true)](https://npmjs.org/package/parse-fraction/)

```js

const parseFract = require('parse-fraction')

parseFract('half') // [1, 2]

parseFract('one third') // [1, 3]

parseFract('seven eighths') // [7, 8]

parseFract('¼') // [1, 4]

parseFract('13 / 15') // [13, 15]

parseFract('19 ÷ 21') // [19, 21]

parseFract('full') // [1, 1]

parseFract('one millionth') // [1 , 1000000]

parseFract('five over six') // [5, 6]

parseFract('zero-point-one-two') // [12, 100]

parseFract('.12') // [12, 100]

parseFract('12%') // [12, 100]

parseFract('tau over phi') // [Math.PI * 2, (1 + Math.sqrt(5)) / 2]

parseFract('one hundred twenty-three thousand four hundred fifty-six one hundred twenty-three thousand four hundred fifty-sixths') // [123456, 123456]

parseFract('fifty-fifty') // [50, 50]
