생활코딩 : JAVA1 - 숫자와 연산

public class Number {
 
    public static void main(String[] args) {
        // Operator
        System.out.println(6 + 2); // 8
        System.out.println(6 - 2); // 4
        System.out.println(6 * 2); // 12
        System.out.println(6 / 2); // 3 
 
        System.out.println(Math.PI); // 3.141592653589793
        System.out.println(Math.floor(Math.PI)); //내림 3.0 찍힘
        System.out.println(Math.ceil(Math.PI));  //올림 4.0 찍힘
         
         
    }
