How to convert a currency string to a double with jQuery or Javascript?

Question

I have a text box that will have a currency string in it that I then need to convert that string to a double to perform some operations on it.

\"$1,1

Answer 1

I know this is an old question but wanted to give an additional option.

The jQuery Globalize gives the ability to parse a culture specific format to a float.

https://github.com/jquery/globalize

Given a string "$13,042.00", and Globalize set to en-US:

Globalize.culture("en-US");

You can parse the float value out like so:

var result = Globalize.parseFloat(Globalize.format("$13,042.00", "c"));

This will give you:

13042.00

And allows you to work with other cultures.

Answer 2

var parseCurrency = function (e) {
    if (typeof (e) === 'number') return e;
    if (typeof (e) === 'string') {
        var str = e.trim();
        var value = Number(e.replace(/[^0-9.-]+/g, ""));
        return str.startsWith('(') && str.endsWith(')') ? -value: value;
    }

    return e;
} 

Answer 3

// "10.000.500,61 TL" price_to_number => 10000500.61

// "10000500.62" number_to_price => 10.000.500,62

JS FIDDLE: https://jsfiddle.net/Limitlessisa/oxhgd32c/

var price="10.000.500,61 TL";
document.getElementById("demo1").innerHTML = price_to_number(price);

var numberPrice="10000500.62";
document.getElementById("demo2").innerHTML = number_to_price(numberPrice);

function price_to_number(v){
    if(!v){return 0;}
    v=v.split('.').join('');
    v=v.split(',').join('.');
    return Number(v.replace(/[^0-9.]/g, ""));
}

function number_to_price(v){
    if(v==0){return '0,00';}
    v=parseFloat(v);
    v=v.toFixed(2).replace(/(\d)(?=(\d\d\d)+(?!\d))/g, "$1,");
    v=v.split('.').join('*').split(',').join('.').split('*').join(',');
    return v;
}

Answer 4

For anyone looking for a solution in 2020 you can use Currency.js.

After much research this was the most reliable method I found for production, I didn't have any issues so far. In addition it's very active on Github.

currency(123);      // 123.00
currency(1.23);     // 1.23
currency("1.23")    // 1.23
currency("$12.30")  // 12.30

var value = currency("123.45");
currency(value);    // 123.45

Answer 5

Remove all non dot / digits:

var currency = "-$4,400.50";
var number = Number(currency.replace(/[^0-9.-]+/g,""));

Answer 6

Here's a simple function -

function getNumberFromCurrency(currency) {
  return Number(currency.replace(/[$,]/g,''))
}

console.log(getNumberFromCurrency('$1,000,000.99')) // 1000000.99
