刚开始晕了，尽然会用BigInteger，后来用BigDecimal轻松搞定，不过，据说用c或者c++有点麻烦。。。。


AC代码：

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

public class hdu2504{
 public static void main(String[] args) {
  Scanner cin =new Scanner (System.in);
  while(cin.hasNext()){
   BigDecimal a = cin.nextBigDecimal();
   BigDecimal b = cin.nextBigDecimal();
   if(a.compareTo(b)==0){
    System.out.println("YES");
   }
   else{
    System.out.println("NO");
   }
  }
  
 }
}
