WARNING : v1.3.2.3 generates calculation errors on customer invoices !

[wwwilliam]

WARNING : Dispite the announcement recently published ie :

quote
The PrestaShop Team is pleased to announce the publication of a new version of PrestaShop, v.1.3.2.
This new version is even richer and contains many improvements and optimizations worked since the v.1.3.1 on the key points of the solution, such as management of rounding, catalog, and SEO .unquote

It is now confirmed that the Rounding, the VAT Calculations and the Volume Discounts are still a major problem in v1.3.2.3 leading to ridiculous differences between orders, invoices and payments.

I just made the move from v1.2.5 to v1.3.2.3 when several recent posts on the forum confirmed that there are still some severe problems resulting from calculations errors.
As off today, despite promisses made, these problems have not been addressed correctly or solved.

Details: on VAT when Volume Discounts are used.
To give you an example, I attached an image. Please have a look at it.

In this case, the customer is asked for necessary information, and needs to fill a text field before adding the product in cart.

The AdminOrder.php file on line 354 :
’.Tools::displayPrice($product[‘total_customization_wt’], $currency, false, false).’
displays correct information.

This same file AdminOrder.php file on line 387 :
’.Tools::displayPrice(Tools::ps_round($product[‘product_price’], 2) * (1 + ($product[‘tax_rate’] * 0.01)) * ($customization[‘quantity’]), $currency, false, false).’
Starts recalculating the same parameter and makes a mistake, and prints it on the invoice mailed to the customer !!!

In the meantime, you should also know that the invoice generator PDF.php makes the same type of strange VAT re-calculations in lines : 471-653-654-676-679-680-760-763-776-779-785-804 & 805 !!!

I am here asking the Team to address this urgently and give us directions on how to resolve this.
I think this is a priority.

How many users are going to freshly install or ugrade to v1.3.2.3 and spend money and weeks of their time to finally discover that the shop does not work as they were told ?

Also remember that many prestashoppers already made the move from 1.2.5 to 1.3.2.3 because we have been told to wait for this version which was free of such mistakes. I do think this is a mistake and not just a bug ! But yes, I filled an other bug report for this.

The new v1.3.2.3 announcement here above should read :
