You can do like this : echo round(66.666666666667, 2); >> 66.66

Use number_format() to specify your decimals and separator. 

     <?php 
        $up=4;
        $down:2;
        $num = (($ups/($ups+$downs))*100).'%'; 
        $formatted_num = number_format($num, 2, '.', '');
       echo $formatted_num;
     ?>
