[SOLVED] 1.4.11 Rounding error

[jgullstr]

Hello,

 

Heads up for 1.4.11 users (since development has stopped):

 

There's a major bug in PS 1.4.11 which causes price calculation errors if you display prices with tax.

When calculating price with tax, taxes are added to the already rounded tax-free price.

(This causes erroneus prices in i.a. order confirmations and invoices)

 

Solution:

/classes/Order.php switch line #446 and #447 i.e.

 

$row['product_price_wt'] = Tools::ps_round($row['product_price'] * (1 + $row['tax_rate'] / 100), 2);

$row['product_price'] = Tools::ps_round($row['product_price'], 2);
