Hi Amol111,

Refer the below code.

HTML

<html xmlns="http://www.w3.org/1999/xhtml">
<head runat="server">
    <title></title>
    <script type="text/javascript" src="https://ajax.googleapis.com/ajax/libs/jquery/1.8.3/jquery.min.js"></script>
    <script type="text/javascript">
        $(function () {
            $('#txtRound').on("change", function () {
                var originalValue = $(this).val();
                var roundedValue = Math.round(originalValue);
                $(this).val(roundedValue);
                var newValue = Math.round((parseFloat(originalValue) - parseFloat(roundedValue)) * 100) / 100;
                if (newValue < 0) {
                    alert("Added value : " + -(newValue));
                }
                else if (newValue > 0) {
                    alert("Substracted value : " + newValue);
                }
                else {
                    alert("No value Added/Substracted");
                }
            });
        });
    </script>
</head>
<body>
    <form id="form1" runat="server">
