[TYPO3-commerce] calculating the article sum price

[Jeroen Visser]

Hi All,
In the webshop that's running it seems that round off is not done as expected.
For example: a article that costs 1.42 inc. Tax and 1.19 ex. Tax on the website I show the 1.19

The following happens when changing the amount in the basket:

€ 1,19	1x	€ 1,19
€ 1,19	2x	€ 2,38
€ 1,19	3x	€ 3,57
€ 1,19	4x	€ 4,77 (should be 4,76)
€ 1,19	5x	€ 5,96 (should be 5,95)
€ 1,19	7x	€ 8,35 (should be 8,33)
€ 1,19	10x	€ 11,93 (should be 11,90)
€ 1,19	20x	€ 23,86 (should be 23,80)

The article settings are:
BTW: 19,00
Net: 1,19
Gross: 1,42

I have tested in class.tx_commerce_basic_basket.php adding ,2 to the functions round() which resulted in the list above. Without round(,2) the
list looks like:
€ 1,19	2x	€ 2,38
€ 1,19	3x	€ 3,58
€ 1,19	20x	€ 23,87

Does anyone else has the same problem? Thank's in advance

Kind regards,
Jeroen
