代码如下:
import java.util.*;
import java.io.*;
import java.lang.String;
import java.math.BigDecimal;
public class p1036
{
public static void main(String[] args)
{
String s1,s2;
Scanner cin = new Scanner(System.in);
s1 = cin.next();
s2 = cin.next();
BigDecimal b1 = new BigDecimal(s1);
BigDecimal b2 = new BigDecimal(s2);
System.out.println(b1.add(b2));
cin.close();
}
}
