Rounding off to two decimal places

Hi. I've just joined the list today so "Hello", etc etc. I'm from an ASP background (argh! that hurt!) and I have a question regarding rounding off a number. I'm trying the following: <td><?echo $font[1].$quota_units_max?></font></td> When this line is executed the value of $quota_units_max is 4.9998350143433. I'd like to display 4.99 (or 5.00, if I have to). on http://uk.php.net/manual/function.round.php it says I should be able to do this: $quota_units_max = round ($quota_units_max, 2); When I try this I get the following error: Warning: Wrong parameter count for round() Any ideas?
