Convert numerical values to currency format

Question

Convert numerical values to currency format

Here is a number 5850 that I would like to format as currency.

Format Example 1:

5850 => $58.50

Format Example 2:

9280 => $92.80

I am utilizing the function below:

Number.prototype.formatMoney = function(decPlaces, thouSeparator, decSeparator) {
    var n = this,
        decPlaces = isNaN(decPlaces = Math.abs(decPlaces)) ? 2 : decPlaces,
        decSeparator = decSeparator == undefined ? "." : decSeparator,
        thouSeparator = thouSeparator == undefined ? "," : thouSeparator,
        sign = n < 0 ? "-" : "",
        i = parseInt(n = Math.abs(+n || 0).toFixed(decPlaces)) + "",
        j = (j = i.length) > 3 ? j % 3 : 0;
    return sign + (j ? i.substr(0, j) + thouSeparator : "") + i.substr(j).replace(/(\d{3})(?=\d)/g, "$1" + thouSeparator) + (decPlaces ? decSeparator + Math.abs(n - i).toFixed(decPlaces).slice(2) : "");
};

After applying the above function, the result obtained is $5,850.00.

If you want to slightly modify the method, you can make some adjustments like the ones shown below:

String.prototype.formatCurrency = function(decimalPlaces, thousandSeparator, decimalSeparator) {
    var num = this,
        decimalPlaces = isNaN(decimalPlaces = Math.abs(decimalPlaces)) ? 2 : decimalPlaces,
        decimalSeparator = decimalSeparator == undefined ? "." : decimalSeparator,
        thousandSeparator = '',
        thousandSeparator = thousandSeparator == undefined ? "," : thousandSeparator,
        symbol = num < 0 ? "-" : "",
        integer = parseInt(num = Math.abs(+num || 0).toFixed(decimalPlaces)) + "",
        length = (length = integer.length) > 3 ? length % 3 : 0;
    return symbol + (length ? integer.substr(0, length) + thousandSeparator : "") + integer.substr(length).replace(/(\d{3})(?=\d)/g, "$1" + thousandSeparator) + (decimalPlaces ? decimalSeparator + Math.abs(num - integer).toFixed(decimalPlaces).slice(2) : "");
};

Utilizing a library to handle currency formatting can simplify the process for you. One option is currencyFormatter.js () - I recommend giving it a try. This library is compatible with all browsers and is lightweight. It automatically adds currency symbols and allows you to format based on a specified locale:

OSREC.CurrencyFormatter.format(2534234, { currency: 'INR' }); 
// Outputs ₹ 25,34,234.00

OSREC.CurrencyFormatter.format(2534234, { currency: 'EUR' }); 
// Outputs 2.534.234,00 €

OSREC.CurrencyFormatter.format(2534234, { currency: 'EUR', locale: 'fr' }); 
// Outputs 2 534 234,00 €

function convertToDollars(n) {
  return (n+"").replace(/(\d{0,2})(\d{2}).*/, "$$$1.$2")
}
