Hi I have following table

```
<table id="rates">
    <tr id="r1" class="edited">
        <td><input type="text" name="f11" value="10" /></td>
        <td><input type="text" name="f12" value="20" /></td>
    </tr>
    <tr id="r2">
        <td><input type="text" name="f21" value="50" /></td>
        <td><input type="text" name="f22" value="60" /></td>
    </tr>
    <tr id="r3" class="edited">
        <td><input type="text" name="f31" value="100" /></td>
        <td><input type="text" name="f32" value="200" /></td>
    </tr>
</table>

```

When input text change I add a class `.edited` to `tr`. What I want is, I want to fixed all the values in `.edited` row to two decimal places after any text change. How can I achive that. Plz help.
