Numbers convert to currency formate

Copy below function in your js.

function formatCurrency(num) {

    num = num.toString().replace(/\$|\,/g,'');

    if(isNaN(num)) num = "0";

  // sign = (num == (num = Math.abs(num)));

    num = Math.floor(num*100+0.50000000001);

    cents = num%100;

    num = Math.floor(num/100).toString();

    if(cents<10) cents = "0" + cents;

    for (var i = 0; i < Math.floor((num.length-(1+i))/3); i++)

        num = num.substring(0,num.length-(4*i+3))+','+num.substring(num.length-(4*i+3));

    return ( num + '.' + cents);

}

call function to get currency formate:

$('#test').html(formatCurrency('123456.98'));

Output:
123,456.98
