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

You can try this

var str = "$1,112.12";
str = str.replace(",", "");
str = str.replace("$", "");
console.log(parseFloat(str));

Answer 2

Such a headache and so less consideration to other cultures for nothing...

here it is folks:

let floatPrice = parseFloat(price.replace(/(,|\.)([0-9]{3})/g,'$2').replace(/(,|\.)/,'.'));

as simple as that.

Answer 3

accounting.js is the way to go. I used it at a project and had very good experience using it.

accounting.formatMoney(4999.99, "€", 2, ".", ","); // €4.999,99
accounting.unformat("€ 1.000.000,00", ","); // 1000000

I know you've found a solution to your question, I just wanted to recommend that maybe you look at the following more extensive jQuery plugin for International Number Formats:

Answer 5

This worked for me and covers most edge cases :)

function toFloat(num) {
  const cleanStr = String(num).replace(/[^0-9.,]/g, '');
  let dotPos = cleanStr.indexOf('.');
  let commaPos = cleanStr.indexOf(',');

  if (dotPos < 0) dotPos = 0;

  if (commaPos < 0) commaPos = 0;

  const dotSplit = cleanStr.split('.');
  const commaSplit = cleanStr.split(',');

  const isDecimalDot = dotPos
    && (
      (commaPos && dotPos > commaPos)
      || (!commaPos && dotSplit[dotSplit.length - 1].length === 2)
    );

  const isDecimalComma = commaPos
    && (
      (dotPos && dotPos < commaPos)
      || (!dotPos && commaSplit[commaSplit.length - 1].length === 2)
    );

  let integerPart = cleanStr;
  let decimalPart = '0';
  if (isDecimalComma) {
    integerPart = commaSplit[0];
    decimalPart = commaSplit[1];
  }
  if (isDecimalDot) {
    integerPart = dotSplit[0];
    decimalPart = dotSplit[1];
  }

  return parseFloat(
    `${integerPart.replace(/[^0-9]/g, '')}.${decimalPart.replace(/[^0-9]/g, '')}`,
  );
}

toFloat('USD 1,500.00'); // 1500
toFloat('USD 1,500'); // 1500
toFloat('USD 500.00'); // 500
toFloat('USD 500'); // 500

toFloat('EUR 1.500,00'); // 1500
toFloat('EUR 1.500'); // 1500
toFloat('EUR 500,00'); // 500
toFloat('EUR 500'); // 500

Answer 6

    $ 150.00
    Fr. 150.00
    € 689.00

I have tested for above three currency symbols .You can do it for others also.

    var price = Fr. 150.00;
    var priceFloat = price.replace(/[^\d\.]/g, '');

Above regular expression will remove everything that is not a digit or a period.So You can get the string without currency symbol but in case of " Fr. 150.00 " if you console for output then you will get price as

    console.log('priceFloat : '+priceFloat);

    output will be like  priceFloat : .150.00

which is wrong so you check the index of "." then split that and get the proper result.

    if (priceFloat.indexOf('.') == 0) {
            priceFloat = parseFloat(priceFloat.split('.')[1]);
    }else{
            priceFloat = parseFloat(priceFloat);
    }
