可以用java大数

 

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

public class Main {

    public static void main(String[] args) {
        Scanner in = new Scanner(System.in);
        BigDecimal a;
        BigDecimal b;
        while(in.hasNextBigDecimal()) {
            a=in.nextBigDecimal();
            b=in.nextBigDecimal();
            a=a.stripTrailingZeros();           //去掉小数点后面多余的0.
            b=b.stripTrailingZeros();
            if(a.equals(b))
                System.out.println("YES");
            else
                System.out.println("NO");
        }
    }
}
