Round help

[Anon]

I am trying to figure out how to force 2 decimal points. I have been using, ie. $a=round($b+$c,2). The problem is when I go to echo them out
print"<tr "bgcolor=\"#ffffce\"><td>$a</td>
I can end up with something like 9.1 instead of 9.10. how can I fource the 2 decimal places. I hope that makes some sense.

$a = sprintf("%.2d", $b+$c);

Note that sprintf returns a string, so $a is a string, not a number.

Thank you Diego, is there an equivalent for numbers?

Diego,

In addition where I use this:

<?php
$a=67.093333;
$b=sprintf("%.2d",$a);
echo $b;
?>

it returns 67 and not 67.09 does it work correctly for you?

Sorry, instead of 'd' use 'f'.
