    <script>
    function txtpercentage() {
    var SumofTotal;
    var Quantity = $('#txt2').val();
    var strarray = Quantity.split(',');
    var numericReg = /^[0-9.*+-/]+$/;
    if (!numericReg.test(Quantity)) {
    alert('Numeric characters only.');
    }
    else {
    var str = Quantity;
    var numbers = str.replace(/ /g, '').split(/[-+*\/]/g);
    var operators = str.replace(/ /g, '').split(/\d*/g);
    operators.shift();
    var result = +numbers[0];
    for (var i = 0; i < operators.length - 1; i++) {

    result = eval(result + operators[i] + numbers[i + 1]);
    if (isNaN(result)) {
    $("#txt3").html(result.toFixed(2));
    }
    else {
    $("#txt3").html(result.toFixed(2));
    }
    }
    }
    }
    </script>

    Hi,

    I am not sure why it is so difficult to do it.
    While adding decimals we need to parse the values.

    So what actually we are doing here like, You have combination of INT and DECIMALS.
    You can convert DECIMAL to INT but data loss is there. But you can convert INT to DECIMALS without any data loss.

    So convert all the INT which is coming as input so obviously you will get the DECIMAL output.

    jQuery(".class #method").change(function(){
    var costing = jQuery(this).val();
    jQuery("#textbox1").val(cost); //suppose returns 20.00
    var totals = parseFloat(cost) + parseFloat(total); //total returns 71.96
    });

    Thanks,
    Mani
