Rounding prices to no decimals

-- url of the page with the problem -- : www.dsgbutiken.com
-- HikaShop version -- : 2.6.0
-- Joomla version -- : 3.4.5
-- PHP version -- : 5.5.28

I administer a web shop where we now run a campaign with 10% discount on the entire web shops products.
But the problem is that the prices in SEK is now rounded to a two decimal value.
How do I get rid of all decimals so only full krona prices are displayed?
It seems like nothing is applying no matter how I try to set the rounding under the currency settings.
Any help highly appreciated.

Hi,
Ok first I thought it was the rounding increment I had to set but found out that it is the Local and International fractional digits that does the trick.
Anyway thanks.
