Question

Hello, I am trying to write a java method for calculating total annual salary. The method receives monthlySalary and monthlySales. The commission is 2% of monthly sales. The output has to be an int rounded to the nearest dollar. I can't seem to get it working and output "1245" instead of "1244.63" Please help!

Answer 1

You can try using Math.round(number)

Answer 2

And you may need to type cast it to turn it into an int.

Answer 3

Thanks, I'll give it a try. I was type casting the double into an int before, but it was rounding to the nearest 1000, ie 12000 from 12120.

Answer 4

The easy way it to have it return the cast of the rounded number. So it takes in the salary and sales, does the math, and returns a rounded number that is cast into an int.

Answer 5

```
public class RoundTest{
public static void main(String[] args){
double a = 12120.682;
System.out.println("Just a: " + a);
System.out.println("Int a: " + (int)a);
System.out.println("Rounded a: " + Math.round(a));
System.out.println("Int of Rounded a: " + (int)Math.round(a));
}
}
```
Got me:
Just a: 12120.682
Int a: 12120
Rounded a: 12121
Int of Rounded a: 12121

The Rounded one might return an int, but by casting it after the rounding, you make sure it returns an int.
