I think i ve found it on file : FOLDER/shemas/exim/products.php





Line 105 :



‘Price’ => array (

‘#table’ => ‘product_prices’,

‘#db_field’ => ‘price’

),





I ve tested (with product inc VAT is product price +21%) but it seems not working :



‘Price’ => array (

‘#table’ => ‘product_prices’,

‘#db_field’ => ‘price’ * 1.21

),



How can i modify it to apply tax please?

Any idea?

I ve found it but the mount is with 5 number after float



‘Price’ => array (

‘#table’ => ‘product_prices’,

‘#db_field’ => ‘price*1.21’

),



return mount is for example 12,12345€

Any idea to round it with 2 digits after float?
