    Question Clarification

    I've been reading this book and it had this code.

    27 double totalPayment = monthlyPayment * numberOfYears * 12;
    29 // Display results
    30 System.out.println("The monthly payment is $" +
    31 (int)(monthlyPayment * 100) / 100.0);
    32 System.out.println("The total payment is $" +
    33 (int)(totalPayment * 100) / 100.0);
    34 }
    35 }

    I just don't understand what is the purpose of the (int) in S.O.P

    I mean the value itself is double, doesn't that satisfy it ?

    EXAMPLES* of some cases to where these can be applied ?

    Thank you in advance!

    Default Re: Clarification

    purpose of the (int)
    That is a cast. It changes the value to an int. What prints when the code is executed?
    Remove the (int), compile and execute it to see what the difference is.
    If you don't understand my answer, don't ignore it, ask a question.
