v150 Order Total takes net price as a base to sum up

[realgs]

Hello,
I am running clean v1.50 version of zencart with standard tax module.
Let's take as an example product which costs 12,59 (net) & 15,49(gross, including 23% tax-> exactly 15,4857)
Order total for 2 products is calculated as below:
(2x 12,59)*1,23 = 30,9714 -> 30,97

And what customer think it should be is 2*15,49 = 30,98.

The funniest thing is that in customer's chart zencart displays 30,98 both in 'total' field & in row with this product.

Is there any option in admin panel responsible for switching the base of Order Total or should I just fix the code? Could you tell me where the total price is being calculated?

This solution only helps displaying our customer the same value in customer's cart as it is stated at the end of placing order. Taking look at the above example- I would like to calculate the total: gross price*quantity.
Proposed solution works as long as the quantity is less than 1000 and as long as store admin keeps 4 decimals of net price.

Could you tell me where to look for order total calculation in code?

I don't know why I can't edit my previous message but just to make it clear. Taking the above example:
Let's assume that we keep 4 decimals of each price.
Having gross price equal 15.49
net price = round(15.49 / 1.23 , 4) = 12,5935

Then a customer wanting to order 1000 such products will see weird price 15490,01
How is it calculated? round(12.5935*1000*1.23 , 2)
I would like to make my zencart calculate the final price taking gross as the basis. That would be 15.49 * 1000 = 15490. Could you point me the place in ZenCart's code where order total is calculated?
