Who Stole My Zeros?!

Here's a quickie for the mathematicians out there...
I'm using a record to perform a calculation that generates a simple product shipping cost. The calculation is the product weight multiplied by a fixed number. Something like this:
<?php echo $record['weight'] * 5 ?>
Although this works fine in practice (and can be used in systems like Paypal, etc.) the figures don't look right.
For example, instead of £2.50 what you see is £2.5!
Instead of £7.00 all you get is £7.
Simple question: How do I rework the code to display the missing zeros?!
:0o

Hi Perch,
We're going to have to use a PHP function for this.
instead of this: <?php echo $record['weight'] * 5 ?>
try this: <?php echo number_format($record['weight'] * 5, 2) ?>
The ", 2" tells it to _always_ show 2 decimals, even then they're 00. This will also add thousands separators. So one million will display like this: 1,000,000.00. If it's a problem we can have it not add those. Let me know what works best for you.
Hope that helps!

Dave -
Seriously, you must stop eating that brainy food and give us mere mortals an opportunity to shine sometimes!
Thanks,
