Some products have prices with several decimal places or below 0.01 that typically are expressed using price unit. Ex.:

Description: Dropper Unit: Each Price: $ 25.66 Price Unit: 1000

That means the actual price of a single dropper is $ 25.66/1000 or $ 0.02566, what cannot be represented unless you extend the number of decimal places to 5 or more. I could not find price unit in the material data, is there a configuration or a module available to provide that?

Notice that 'Price Unit' is different from 'Unit Price'.
