When a product has a discount, on my invoice it shows for example -30.250000.

What can i do to get only -30.25 ?

What is your version? What number of decimals do you have set under Preferences > General?

Version 1.6.0.8, that does not have the option to change it like the 1.6.1.1 (i have a second shop where i can compare.

The 1.6.0.8 shop i cannot update so i need to go into the core files somewhere.

Do you know in what file i can change this?

Invoices have files under /pdf and /classes/pdf directories.

I think it must be around here:
 

{if (isset($order_detail.reduction_amount) && $order_detail.reduction_amount > 0)}

-{$order_detail.reduction_amount}

{elseif (isset($order_detail.reduction_percent) && $order_detail.reduction_percent > 0)}

-{$order_detail.reduction_percent}%

{else}

So now i need to know where i change the result of $order_detail.reduction_amount so it only shows $,$$ instead of $,$$$$$$$
