8 – How to round the total price, display without decimal?


I need to count on decimal places (tax, promotion, fee …), but the total price must be mathematically rounded without decimals.

Example:
2 x product1 CZK 424.00
1 x Product2 CZK 408.00

Subtotal CZK 832.00
Shipping CZK 99.00
Discount CZK -41.60
10% VAT CZK 71.86
21% VAT CZK 17.18
-Total CZK 889.40- remove
Rounded CZK – 0.60 it is not necessary to display
Total CZK 889.00
