Discount percentage not rounding up correctly on items

Hi,

Thanks for your plugin.

I have a client that is interested in the premium version. The only issue they are experiencing is that items that are discounted by percentage are not rounding up. For example, this item: https://greenltg.com/product/ushio-hilux-gro-ahs-de-1000w-pro/. When 6 items are added to the cart, a 4% discount is applied. Each item would be 67.25, but it is charging 67.247. Is it possible to round this up? So that it charges what is listed?

Thanks!
