I need some advice on formatting numbers using PHP.

My database holds numbers like:

10
0.2

I need these to be displayed as

10.00
0.20

I'll add the '£' sign, so the end result is

£10.00
£0.20

How do I do that. ? The vaule are coming from $number


Also some of the numbers may be negatives:

-0.3
-5

Is there any easy way to detect negitives ?

Ideally I'd like to be able to show positive number in one color and
negitive in red on screen.

Thanks :)

<code>
if ($number < 0)
{
$color = "red";
}
else
{
$color = "green";
}
</code>

or

<code>
$color = ($number < 0) ? "red" : "green";
</code>

Hi,

Here is an example using sprintf, straight from www.php.net
http://nl3.php.net/manual/en/function.sprintf.php


<?php
$money1 = 68.75;
$money2 = 54.35;
$money = $money1 + $money2;
// echo $money will output "123.1";
$formatted = sprintf("%01.2f", $money);
// echo $formatted will output "123.10"
?>
