So I want to display the following zeros in a 2 precision php rounded number, but I need it as a numerical...how do I do that?

i.e.

PHP Code:

$amount = 1;
$exchange = 1.5;
$total = round($amount*$exchange);

echo $total; 


how do I get that to display as 1.50 as a numerical (as opposed to the string that the number_format(); function gives)?
