Why am I getting a rounded output when running this code?

Question

I am trying to have this code convert inches to feet, but whenever I try and get an output I find it is rounded down even though I am returning it as a float.

I have tried changing the code to do the modulus function + the division function, but the only gave the remainder. I am new to code so this is probably really easy just can't seem to figure it out.

``````````````````JAVA````````````````````````````````` //this is the method that I using to output.

public static void main(String[] args) {
    System.out.println(calcFeetAndInchesToCentimeters(34));
}

//this is the method I am actually using to calculate.

public static float calcFeetAndInchesToCentimeters(int inches){
    if(inches >= 0){
        return inches / 12;
    }else{
        return -1;
    }
 }

output: 2.0



I would like to have the output be when I run the code above 2.83, however, I am only getting the rounded down version. I am not trying to find a

Use one of the parameters in `return` as float: `return inches / 12.0f;` — Susmit Agrawal, May 15 '19 at 18:31

you can cast integer to float and then try

public static float calcFeetAndInchesToCentimeters(int inches){
    if(inches >= 0){
        return (float)inches / 12;
    }else{
        return -1;
    }
 }

You are passing an integer to the method and dividing by an int so the result will always be an int. To fix this just change your method to:

    public static float calcFeetAndInchesToCentimeters(float inches){}

Typecast inches to float and then divide.

public static float calcFeetAndInchesToCentimeters(int inches) {
    if (inches >= 0) {
        return ((float) inches) / 12;
    } else {
        return -1;
    }
}
