[SOLVED] Decimal Points?

[stublackett]

Hi,

 

I've got a shopfront working (As you may have gathered from previous posts by me)

 

My next issue is with it only allowing 10% discount I'm getting a 3 points after a number eg 10% of £13.43 is coming out as £12.087

Ideally I'd like that to come out as £12.08

 

How do I achieve this?

 

My code to calculate the 10% is :

 

<?php //Check for discount

$amount = $_SESSION['total_price'];

$discount = $_POST['value'];

if ($discount == "TQ") { 
$total = $value;
$discount = 0.9;
$newtotal = $amount * 0.9; 

// save back to session variable total_price
$_SESSION['total_price'] = $newtotal;


?>

After '$newtotal = $amount * 0.9; '

add '$newtotal = round($newtotal, 2);'

 

Kurrel,

-All smiles.
