Use **parseInt(document.getElementById("value"));** instead of 10 to get the result on value given in TextBox — Sam1604, Feb 03 '14 at 07:31

you are missing this

function sample() {

              var num = parseFloat(document.getElementById("value").value);//read the textbox value
            var result = num.toFixed(2);
            document.getElementById("value").value=result;//it will bind the result to the textbox


        }

Try this, It works fine as you need,

            function sample() {
                var num = parseInt(document.getElementById("value").value);
                var result = num.toFixed(2);
                document.getElementById("value").value = result;
            }

Try the following, It might be helpful for you.

<script type="text/javascript">

$("#number").each(function(){
  $(this).val(parseFloat($(this).val()).toFixed(2));
});

</script>
