How to remove price rounding in opencart/ocStore 2+?

Question

opencart

Hello, tell me how to remove price rounding and "extra" zeros after the decimal point in opencart / ocstore 2+. There are no problems with whole numbers, but if you put 10.50, it rounds up to 11, if 10.30 then up to 10.
The question of the number of characters after the decimal point is also of interest, now there are 4 characters after the decimal point, how can you limit from 4 to 2 characters, thanks!

I figured it out ... in the admin panel in the currency we put the stake -in the sign after the comma - 2 and everything worked.
