How to remove decimal point from price

-- url of the page with the problem -- : li-art.com/new/index.php/en/shop
-- HikaShop version -- :2.3.0
-- Joomla version -- : 3.3.0

Hello,
The prices of the products in the shop I'm building are round and therefore don't require a decimal point. How do I show the prices without it?

Thanx

Thanks
