What is your question? What stops you from using them the same way as integers?

Floats are used for decimal numbers. Generally for precision it is better to use Double. Long nor Int can hold decimal places where float and double can.

How would I write System.out.println(3 + 2 + 1 - 5 + 4 % 2 - 1 / 4 +6) using floating numbers?

there's no reason for using a floating number there. it's an integer. I'm not sure I'm picking up on the fascination with floating numbers here. it's just a data type and you declare and utilize it like any other, it just happens to store a decimal as well.

if I calculated that correctly it comes out to 6.5. I'm just trying to figure out how to write them properly. I'm lost

No its 7.0. There's no difference writing them as opposed to any other variable such as int, char etc. try this: public class main { public static void main (String[] args) { float num; num = 3 + 2 + 1 - 5 + 4 % 2 - 1 / 4 + 6; System.out.print (num) } }
