Bug: A very dangerous one: Totals with rounding error

Hello,

There is a very nasty bug when it comes to adding items with options to the cart.

I did this test with V0.7.6

I added the red MINIMOTO1 (that comes on the sample database after install) with two options:

Color -> Red  (this adds 1.18 to the price)
Size -> Small  (this adds 3.53 to the price)

The price for the item is: 117.50

If you add those numbers together (1.18 + 3.53 + 117.50) the total is: 122.21 right?

But the actual cart gives a total of: 122.20 !!!

Let everyone know because this is a big problem on high traffic shopping sites.

Also, if anyone is interested, I have implemented an "add to cart" and a "details" button to each product inside the categories and on the front page, so users can quickly click "add to cart" instead of having to click to the details page then click the "add to cart" button.

Thank you

The correct calculation is made in v0.7.7
