Parse any float number from within a provided text.

#parseFloats within text input#

Parse any float within a text by simply calling the method:

###Code:###

parseFloats('This was our 10th anniversary and I have spent $812,34 on a fancy dinner at the best 7th avenue restaurant.');

###Ouput:###

[ 10, 812.34, 7, min: 7, max: 812.34 ]

Use the convenience attributes min and max to retrieve the high and low values from the generated array. Works great for currencies ;)

parseFloats.js

function parseFloats(str) {
    /*jslint regexp:true*/
    str = (str || '').replace(/[\x80-\xFF]|&.{0,}?;/g, '') || '';
    var m = str.match(/[0-9]{1,}(\.|,)?([0-9]{1,})?(\.|,)?([0-9]{1,})?/g) || [];

    m = m.map(function (item) {
        item = item.match(/(\d+)((,|\.)(?!.*(,|\.)[0-9]))?/g).join('').replace(/\.|,/, '.');
        return parseFloat(item, 10);
    });

    m.min = Math.min.apply(Math, m);
    m.max = Math.max.apply(Math, m);
    return m;
}
