An e-commerce app totals prices as floats:

class Cart {
  public static int checkoutCents(float priceA, float priceB) {
    float total = priceA + priceB;
    int cents = (int) (total * 100); // rounding/truncation risk
    return cents;
  }
}

How can the casting from float to int affect the calculation?
