*urgent* Show with decimals on cart but not in product view

[prehn]

Hello!

Having a big problem that i need help with asap.

I need to show the price in product page without any decimals like this:

Product price: 39:-

But in the cart view i need to show the decimals so that the vat calculation (swedish vat 25%) will get right and i can show the exact sum of the vat like this:

Product price: 39:-

Total VAT/TAX: 7,8:-.

If i dont show decimals on the product total price the vat will be rounded, and i dont want to show the decimals on product page, only in the cart to clarify the exact amount of vat.

Hope you get what i am after.
