Returning integers

Elementary question from a newbie.

I'd like the following operation to return an INTEGER value, ie, no decimals:

<?php if($_POST["submit"])
{
$result2 =(($_POST['dheight']/ $_POST['oheight']) *100);
echo "Multiply the height by: $result2"." %";
}?> 

Code (markup):

 

http://uk2.php.net/round

$result2= round($result2, 0);
echo "$result2";

PHP:

 

Or (int)$result2 but rounding is nicer IMO.

 

Little but very usefulll help. Thanks.

 

Fab! I used the rounding code and it's working. You guys are great, thanks a million.
