Thread: Adding doubles and ints.

What have you tried?

System.out.println(4.4 + 1);

What does that output?

Why are you bothering with ints? Why not just convert everything to double?

I actually didn't know you could do that with the System.out.println command. Sorry, I'm still a bit new at this, I've only known Java for like a month.

Edit
Actually, that wouldn't work if 4.4+1 is part of a bigger expression.
You're right about the doubles though.

It has nothing to do with the println method and everything to do with math.

int one = 1;
double fourPointFour = 4.4;
double result = fourPointFour + one;

Works just fine too.

The two serve different purposes, and people who really care about memory don't want to use something they don't need. "NOT separating the two" would be a horrible idea.

What the heck are you talking about? 4.4 + 1 will produce 5.4 every single time regardless of where you place it in your code. Unless you have 4.4 + 1 * 3.2 in your expression. That of course would produce a different result due to operator precedence but the result will still be a double and you can still add, multiply, subtract and divide ints and doubles.
