How to modify Magento 2 in order to be able to show 4 digit prices and tier prices in the admin catalog? I can save 4 digit prices and they go in the database, even when I load a product edit form in the admin I can see a JSON on the source of the page which contains my 4 digit prices, but in the form itself the prices are all rounded to 2 digits. How can I get the form to show my 4 digit prices without rounding them down to 2 digits?
Hey after hours of searching I finally found how! its in vendor/magento/zendframework1/library/Zend/Currency.php line 74!
change this bit:
protected $_options = array( 'position' => self::STANDARD, 'script' => null, 'format' => null, 'display' => self::NO_SYMBOL, 'precision' => 2, 'name' => null, 'currency' => null, 'symbol' => null, 'locale' => null, 'value' => 0, 'service' => null, 'tag' => 'Zend_Locale' );
'precision' => 2, for
'precision' => 4,
Now I just need to figure the right way to apply this change from a clean module.
