Wierd bug?

[Geert-K]

Ok, here's the deal. When I go to my cart and the Quantity of products is..say.."1" and I change it to 3 or 4 or 5 or whatever there's nothing wrong..

But just try to type in 1.5...or 1.7 or 2.7 it actually does the calcalation for 1.5 x (product price) = total

 

So say a product is 100 euro.

I have the product in my basket..

I change the quantity to 1.5 and end up with 150 euro?!?!?!

 

Is there anyway of changing this? Cause with a comma (,) it is disabled like it should be..
