Double with only 4 decimals???

Question

Hi, this is really a simple question.
I am trying to list a price list of a few items.
Each item has an individual price in double primitive type, (for example the
price of item1 is 2.45).
When I calculate the total of each item in a list and add all together to get
the lists total I sometimes get a total value with a lot of decimals, like this
for example 24,00000000003.
Now how can I make it with only 4 digits, like this for example, 24,00.
Below is an example of an item , just to give you an idea.
Also, a list has many items.
Thanks!
public class Item{
  private int quantity;
  private double total;
  private double price;
  public Item(){
public double getTotal(){
   total = price * quantity;
   return total;
}
