VAT calculation fault in Virtuemart


Our homepage is made with Joomla 1.5 and Virtuemart 1.1.3. When a customer places an order the VAT (19%) on the total orderprice is automatically calulated by the script.

Our program to make invoices calculates the VAT correcly. But the website has a difference of € 0,01. That's not much but that is very frus.

Sometimes the both prices are equal and sometimes they are not. I think this is a round-off issue, but I don't know where I can find or change this.


Correct Calculation:

Order sub-total : € 78.30

Invoice costs : € 10.50


Order total (excl. VAT): € 88.80

VAT (19%) : € 16,872


Order total (incl. VAT): € 105,672

Wrong Calculation:

Order sub-total : € 78.30

Invoice costs : € 10.50


Order total (excl. VAT): € 88.80

VAT (19%) : € ?


Order total (incl. VAT): € 105,68

I hope this would be clear enough to understand my problem.

Can anyone help me with this?
