I am writing a code for a user to choose numbers in a progress bar. For some reason the progress bar does not fill up or empty when the int progress is not exact.

For example: The progress bar value is 5 at the moment. The user chooses 250 Million Cars whose progress value is 7 but the progress bar does not empty. Is there an algorithm or a method that can fix this problem

Thank you.

    private String[] newnumbers = {"Add 250 Million","Add 500 Million","Add 1 billion","Add 1.5 Billion","Add 2 Billion","Remove 250 Million", "Remove 500 Million","Remove 1 billion", "Remove 1.5 Billion", "Remove 2 Billion"};


    private String[] numbers2 = {"Add 100 Million", "Add 500 Million","Add 1 billion","Add 50 Billion"};
