If you return a double it will always add the .0 at the end. You want to return an int like this:

public int getTemp() {
        return (int)Math.round(mTemp);
     }

did you cast values in getters to int ?

this is my get temp method:

getTempMethod.java 
  public double getTemp() {
        return (int)Math.round(mTemp);
     }

but the funny thing is: I didn't get an error when I typed the code BEFORE I added the int cast.

James, you need to set the return type of getTemp() to int instead of double.
