Hi

I have a big file with lines like below

<tr align="center" bgcolor="SEASHELL"><td>94% </td><td>4.62178 </td><td>73.4375 </td></tr>
<tr align="center" bgcolor="SEASHELL"></td><td>97% </td><td>3.2962 </td><td>125 </td></tr>

I want to format the file such that i get like below. i.e retain upto two point decimal where it sees decimal point

<tr align="center" bgcolor="SEASHELL"></td><td>94% </td><td>4.62 </td><td>73.43 </td></tr>
<tr align="center" bgcolor="SEASHELL"></td><td>97% </td><td>3.29 </td><td>125 </td></tr>
