I have a slight problem. I try to offer round numbers including taxes (common in the NL). The VAT tariff in the Netherlands is 19%. For products I can specify the item price with multiple digits. However, it appears to calculate the final price using only the first two digits.
Example: One of my items costs €12,= incl VAT, the price w.o. VAT would then be €10,084034
When making an invoice for two items, the system yields €23.99 in stead of €24.00
