Central storage of decimal prefs

Why isn’t there a preference for decimals? I have products that have a per piece price with 4 decimals ( for example 0.5275) and this is not possible. I already changed a bunch of php code to make this possible, but there keep popping up pages that have 2 decimals in them. Extremely annoying. This could have easily been programmed by adding a central “product price decimal” preference settings. In my case, I only need it for the per piece price of products, the total amounts need to have 2 decimals.
