How do i round up the value so that i can get as 0.42%

A:
You can use the round built in function:
$myFloat = $row['col1']/$row['col2'];
$result = round($myFloat, 2);

Well, the second parameter shouldn't have quotes round it, and to me, the first parameter is ambiguous: does the author mean ($row['col1']/$row['col2'])*100 or $row['col1']/($row['col2']*100) ?
