import java.util.Scanner;

public class Q4
{
    public static void main(String args[])
    {
        float a,b,s;
        double x;
        Scanner sc=new Scanner(System.in);
        System.out.println("Enter 2 decimal numbers");
        a=sc.nextFloat();
        b=sc.nextFloat();
        s=a+b;
        x=Math.floor(s);
        System.out.println("Floor value of sum = " + x);
    }
