Magento-发票/ be中的小数点

Question

I need for my shop up to 4 decimal points. So far I followed some tuts and theyre working fine in front & backend for products. Only in sales/invoice prices,tax and totals are still rounded to 2 decimal points.

I've edited/overwrote following files:

\app\code\local\Mage\Adminhtml\Block\Catalog\Product\Edit\Tab\Options\Option.php

somewhere around line 283 i changed return number_format($value, 2, null, ''); in return number_format($value, 4, null, '');

\app\code\local\Mage\Adminhtml\Block\Catalog\Product\Helper\Form\Price.php 

same as in Option.php

\\app\\code\\local\\Mage\\Core\\Model\\Store.php* changed output of function roundPrice() line 740 into return round($price, 4);

\\app\\code\\local\\Mage\\Directory\\Model\\Currency.php in function format() changed formatPrecision from 2 to 4 in line 197.

\\lib\\Zend\\Currency.php $_options['precision'] changed from 2 to 4

\\app\\design\\adminhtml\\default\\default\\template\\catalog\\product\\edit\\price\\tier.phtml echo sprintf('%.2f', $_item['price']); changed to sprintf('%.4f', $_item['price'])

Ive looked into some core files like invoice.php or in adminhtml files if there are rounding stuff. But I couldnt find anything useful.

used extensions: (Magento 1.4.1.0)  
Asperience_DeleteAllOrders  
Flagbit_ChangeAttributeSet  
Mxperts_Invoice  
de_DE languagepack  

thanks, greetz Rito

Answer 1

My first suggestion would be to turn on the Frontend and Backend Hints ( System>Config>Advanced>Developer ) so you can see which Block and which phtml View is responsible for rendering the 2 decimal place content. If you install the Developer Toolbar extension , you'll find that much easier.

Looking at your screenshot, I think that comes from the Admin Sales Order view, and therefore the phtml files under app/design/adminhtml/default/default/template/sales/order/create/totals and the Blocks = Mage_Adminhtml_Block_Sales_Order_Create_Totals_Default are a good place to look. The formatPrice function seems to be using Store.php that you have overridden, and some of the Currency files.

I suspect that @greg0ire is correct, this one is going to take some remote debugging to track down. It's possible that your $options['precision'] is being overwritten somewhere, so you need to see it's value at the time of execution.

Good luck, JD

PS I assume you have cleared and disabled cache... Note that the adminhtml cache is not cleared in the System>Cache Management GUI, you must manually delete the files in var/cache .

Answer 2

"totals" was a good hint, thx to Jonathan Day

Heres the solution for sales/invoice with four decimal points.

\\app\\code\\local\\Mage\\Adminhtml\\Block\\Sales\\Items\\Abstract.php
change following code:
Line 292: function displayPrices() change to return $this->displayRoundedPrices($basePrice, $price, 4, $strong, $separator);
Line 305: $precision=2 into $precision

\\app\\code\\local\\Mage\\Sales\\Model\\Order.php line 1358:

public function formatPrice($price, $addBrackets = false)
    {
        return $this->formatPricePrecision($price, 4, $addBrackets);
    }

I know its very dirty, but it works fine :)

Answer 3

Found out a different simple way in magento 1.5.1

Got to code/core/Mage/Directory/Model/Currency.php

change line number 194.

public function format($price, $options=array(), $includeContainer = true, $addBrackets = false) { return $this->formatPrecision($price, 0, $options, $includeContainer, $addBrackets); }

0 - Denotes the precision point for price.
