Math average.

[SOLVED]


Im trying to calculate the average, but it discards the remainder.
Have a look.


//Reads a file, and gets the students name + 3 exam grades.
//Then calculates the average grade.

String name;
int grade1;
int grade2;
int grade3;
double average;


TextIO.readFile("result.txt");
name = TextIO.getln();

grade1 = TextIO.getlnInt();

grade2 = TextIO.getlnInt();

grade3 = TextIO.getlnInt();


average = (grade1+grade2+grade3)/3;

System.out.printf("The average grade for %s was %1.2f", name, average);
System.out.println();

I've managed to work around it by just adding them up and dividing like this:

average = (grade1+grade2+grade3);
average = average / 3;
With this i can display the correct value.

I used jEdit, for my coding. And this is a question or "Test yourself" thingy from a book, and the solution uses the same code... so what did i do wrong ?
HELP !

I don't think we could stop you from hanging here if you weren't. Though this community is free, and everyone is welcome.

As long as you're not looking for a handout, questions are accepted here. From the looks of it, you won't have a problem asking questions here.

You are more than welcome here, especially if you keep answering your own questions (and maybe a couple of questions from other newbies)!
