题意很简单，但是涉及到的位数非常多，其次是前导零，然后是精度的后导零，给组样例：

0000123.555  000000000000000000000123.55500000000000000000000000000000000000000000

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

public class Main {

	public static void main(String[] args) {

		Scanner cin = new Scanner(System.in);
		while (cin.hasNext()) // 多组输入
		{
			BigDecimal a = cin.nextBigDecimal();
			BigDecimal b = cin.nextBigDecimal();
			if(a.compareTo(b)==0)System.out.println("YES");
			else System.out.println("NO");
			
		}
	}
