    You're using ints to do double calculations. With integers, 1/3 is 0. 1-0 is 1. 4 * 1 is 4, so you get 4.0.

    To see this better, do it in a few steps:
    int step1 = 1/3;
    System.out.println(step1);
    int step2 = 1 - step1;
    System.out.println(step2);
    int step3 = 4 * step2;
    System.out.println(step3);

    double tmp = 0.3;

    to use 1/3?
