help me with my php scripting?

--------------------------------
<em><?=round( filesize($leadon.$files[$i])/1024 );?>KB</em>
--------------------------------

in the above code, how can i change KB into MB and round to 2 decimals? I found the below code which says it does it but i have no idea how to replace the above to include it... Also, I know instead of 1024 i'd need 1048576 (i think).

--------------------------------
float round ( float $val [, int $precision = 0 [, int $mode = PHP_ROUND_HALF_UP ]] )
--------------------------------
THANK YOU Colanth, it worked like a charm! I'll get u yr points once yahoo lets me choose best answer. ;P

<em><?= round(filesize($leadon.$files[$i]) / 1048576, 2);?>MB</em>

I didn't run it (it's a bit of a pain to save it to a file, upload it to my local server, give it a value, etc.), but it should work. (The spaces around the division sign - ) / 1048576 - are just to keep Yahoo from eating characters.)
