Hi kaarthikeyan,

According to your description, I suggest that you could also use Math.round().

Here is a testing demo.

    <script>
        var num = 100 / 11111;
        var result = Math.round((num + 0.00001) * 100) / 100
        console.log("result:"+result);
    </script>

result:

Best Regards,
