[Typo3-shop] Tax calculation incorrect?

[Franz Holzinger]

Hello Robert,


> In our soon-to-be online shop the price without tax (PRICE_TOTAL_NO_TAX) 
> is not calculated correctly.
> We use these settings for the price calculation:
>   TAXpercentage = 16.00
>   TAXincluded = 1
> 
> Example:
> When the total price (PRICE_TOTAL_TAX) is 10.00 euro, then the price 
> without tax (PRICE_TOTAL_NO_TAX) is calculated as '8.62', but the 
> correct amount would be '8.40' euro. The difference is 0.22 euro.
> 
> With a product that costs 1000 euro (PRICE_TOTAL_TAX), the 
> PRICE_TOTAL_NO_TAX is calculated as 862.07 euro, but it should be 840 
> euro. The difference of 22.07 euro is a bit more significant.
> 
> Is anyone else experiencing this? Where does this difference come from?
> 

the total prices also include the prices for shipping and payment costs.
Each has its own tax settings.
This is calculated in the function getCalculateSums .
