Thread: Clarification

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


27 double totalPayment = monthlyPayment * numberOfYears * 12;
28
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!

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.
