Shopping Cart Rounding Problem with products priced at 0.098 and qty pricing

[lmax401]

Trying to complete the upgrade from v139h to v150 and having rounding issue in the shopping cart.
v150 Site: maxwelldirect.com/store2
Item page example: http://www.maxwelldirect.com/store2/...roducts_id=429
The product is: 225: Weekly Time Card
The prices displayed on the product info page are correct.
250= $24.50
500= $38.50
1000= $63.88

Price Manager Settings for this item:
Price Each: .098, Qty Min: 250, Qty Units: 1, Price by Attribute: No
Discount Type: Percentage
250= 0.00,
500= 21.4286%
1000= 34.8214%

Priced Displayed in the Shopping Cart:
250= $25.00
500= $40.00
1000= $60.00

If the currency decimal is changed from 2 to 3 or 4, different amounts will show for both and not what they are suppose to be.

Do not have this problem in the current version v139h.

Please advise

Could sure use some help with this problem or is this something that can not be fixed in v150?

I am looking into this right now and will be posting a solution as soon as possible ...

Sorry to keep you hanging ... but I have reproduced this ... I just need to ensure the fix does not trigger other issues somewhere else ...

Thanks for your patience on this ...

What happens if you edit the file:
/includes/classes/shopping_cart.php

and around line 852 change the code from:

      $this->total += zen_round(zen_add_tax($productTotal, $products_tax), $decimalPlaces) * $qty;
      $this->total += zen_round(zen_add_tax($totalOnetimeCharge, $products_tax), $decimalPlaces);

to read:

//      $this->total += zen_round(zen_add_tax($productTotal, $products_tax), $decimalPlaces) * $qty;
      $this->total += (zen_add_tax($productTotal, $products_tax)) * $qty;
//      $this->total += zen_round(zen_add_tax($totalOnetimeCharge, $products_tax), $decimalPlaces);
      $this->total += (zen_add_tax($totalOnetimeCharge, $products_tax));
      $this->free_shipping_price += zen_round(zen_add_tax($freeShippingTotal, $products_tax), $decimalPlaces) * $qty;

And if you change the code in the file:
/includes/modules/pages/shopping_cart/header_php

to have the code:

//echo 'I AM HEADER_PHP final_price: ' . $ppe . '<br>';
//  $ppe = zen_round(zen_add_tax($ppe, zen_get_tax_rate($products[$i]['tax_class_id'])), $currencies->get_decimal_places($_SESSION['currency']));
// Ajeh - Tax fix?
  $ppe = ((zen_add_tax($ppe, zen_get_tax_rate($products[$i]['tax_class_id'])) ));

Does this fix the display on the shopping_cart.php?

Does your checkout_payment and checkout_confirmation work right?

Ajeh:
Thank you again for following up on this.
Have applied the changes you sent and the shopping cart is now displaying the correct prices however, the Sub-Total line amount at the bottom of the box is not correct.
Example:
250 = $24.50, Sub-Total is showing $49.50
500 = $38.50, Sub-Total = $78.50
1000 = $63.88, Sub-Total = $123.88

Have no taxes installed so, I can not determine where the additional amount is coming from.
The cart goes back to the original problem after removing the updates above.

Do you have these changes on your server right now?
