A == B ?

1 2
2 2
3 3
4 3

NO
YES
YES
NO

java大数真是开挂般的存在啊

如果用c做的话  不要忘记00005=5,0.5000=0.5

import java.math.BigDecimal;
import java.util.Scanner;

public class Main {

    public static void main(String[] args) {
        // TODO Auto-generated method stub
        Scanner sca=new Scanner(System.in);
        while(sca.hasNext()){
            BigDecimal a=sca.nextBigDecimal();
            BigDecimal b=sca.nextBigDecimal();
            String num1=a.stripTrailingZeros().toString();
            String num2=b.stripTrailingZeros().toString();
            if(num1.equals(num2)){
                System.out.println("YES");
            }
            else{
                System.out.println("NO");
            }
        }
        sca.close();
    }
}
