How do I use floating numbers?

Question

can anyone give me an example of how to properly use floating numbers.

Answer 1

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

Answer 2

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.

Answer 3

float num = 3.5f

for example

Answer 4

I'm just not sure how to use them. what symbol is a floating number in a string? I apologize I just started

Answer 5

how would I write a floating number then ?

Answer 6

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

Answer 7

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.

Answer 8

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

Answer 9

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)
}
}
