Opencart 2.3 - how to change value 00.00r to 0.r in cart button common/cart.tpl?

Question

opencart

Good time
everyone Opencart 2.3
when the cart is empty, on the button (common/cart.tpl carts) in the header there is a value of 00.00r
where and how you can change it to this 0.r if the cart is empty.
in the language file I left only this parameter %s, i.e. it pulls the values ​​00.00r for an empty basket
In the catalog I need these values, after the dot .00 , so it’s not an option to disable it through the currency settings,
how can I do this?
