PHP - Numbers to two decimal places?

Hi,

I've made a script, it's a fruit machine. It takes away $1.00 from your account, and that it your balance. You then spin the reel. If you lose, it removes $0.20 from your balance. If you win, depending on the winning icon, you recieve $x.xx.

Now, I want the balance value to always be shown in two decimal places.. but sometimes it doesnt do this..

For example, when it is on $0.00, it shows up as: $00
Also, when it should be $15.00 it shows up as $150

All other times it shows up normally like $13.20 and $8.70

How do I make it so the numbers always go to 2 decimal places?

Cheers, Cheeko

can you supply some code?

PHP Code:

---

$cash = 12.551;
$cash = number_format($cash, 2);
//$cash now equals 12.55

Code:

---

<?
// Seed the random generator
srand((double)microtime()*1000000);

// Take his money
// Enter code removing Ð1.00 from his account in sql
if (!isset ($balance)) {
$balance = 1.00;
$win = 0.00;
}

if ($balance < 0.20) {
//Remove another Ð1.00 ;)
$balance = 1.00;
$win = 0.00;
$info = "After losing it all, You loaded another Ð1.00 into the slots..";
}

Thats that code..

Even after using that number_format, i Still get 00 for 0.00 and when it wins instead of ebing say 17.50 its 17.500

Also, Im using Ð instead of $ ;) :D

well it worked fine for me. it had 15.00 on it but the only thing I noticed was that when I lost it would be like this 14.8, that is probably an internal php thing, kike the calculator how it take the last zero off. other than that it worked fine. good job.

I don't think you noticed but you have an extra zero in this line

Code:

---

<td align="center" valign="middle" colspan="3"><font face="Verdana, Arial, Helvetica, sans-serif" size="5" color="#F4F4F4"><? echo "$result"; ?> - You have Ð<? echo "$balance"; ?>0

---

Hmm.. I didnt notice that! Cheers mate :)
