Adding a zero after computation

Hi Everyone I've come across a little problem
I've been working on a simple shopping cart
and so far so good but after computing the
totals they do not appear as floats with 2 decimal
places (£2.50 is £2.5)..how can i avoid this problem.
Please help

Here's my code:

Code:

---

$total2=$light_packages * $price2 * $years_light;

---

add this after that line:

PHP Code:

---

$total2 = number_format($total2, 2); 


---

EDIT:
you may also want to look at this http://us3.php.net/manual/en/function.money-format.php

your welcome :)
