I am not sure if you have noticed this, but every release of osCom has this, the text box where you specify the quantity of products, the shopping_cart.php, there you can specify products with decimal places, so a customer could mistakeably orders 2.5 shirts, now I dont know how to give a customer 2.5 of any item, and the weird thing is, the price total includes the price for that 0.5 shirt, so this is what you do,

In includes/classes/shopping_cart.php around line 99 
make sure that the variable 'qty' has (int) in front of it so it looks like,  

[quote]if ($this->in_cart($products_id)) { 
$this->update_quantity($products_id, [quote](int)[/quote]$qty, $attributes);[/quote]

if you are using CVS2.2 then add (int) in catalog/shopping_cart.php around line 149

[quote]$info_box_contents[$cur_row][] = array('align' => 'right',
                                             'params' => 'class="productListing-data" valign="top"',
                                             'text' => '<b>' . $currencies->display_price($products[$i]['final_price'], tep_get_tax_rate($products[$i]['tax_class_id']), [b](int)[/b]$products[$i]['quantity']) . '</b>');
    }[/quote]

Now if someone tries to enter 2.6 or any quantity with decimal, it would round the quantity and the price would not change :idea:
