To round numbers, you can use the sprint function.

<BLOCKQUOTE><font size="1" face="Arial,Helvetica,sans serif">code:</font><HR>


$a = 124.316343;
$b = sprintf("%.2f", $a);

print $b;

# prints 124.32
</pre><HR></BLOCKQUOTE>

You can change the number of decimal places by changing the 2 in "%.2f" to the number of decimal places you want to use.
