More than two digits on the right side of the decimal

[ErikKoedijk]

When giving a product a unit price that has more than two digits on the right side of the decimal, this rounds to the hundredths place. 

This means that we cannot give our products the right price. For example:

Unit price = 0,063766 --> 0,06

0,06 * 5000 = € 300

While the price is: 0,063766 * 5000 =  € 318,83

It will help us if this number rounds like Excel does.
