Panterzone always stores prices internally as a decimal value and converts them to cents for payment providers such as Stripe. For display in the shop, a simple rule applies: whole amounts show without decimals (e.g. "100" instead of "100.00"), while amounts with cents show exactly two decimal places (e.g. "15.95").
The amount you see in the cart and at checkout is always the real price, just formatted differently.
