Java BigInteger remainder()方法

java.math.BigInteger.remainder(BigInteger big) 方法返回一个BigInteger，其值等于(此BigInteger % big(作为参数传递的BigInteger)).余数操作找到此BigInteger除以作为参数传递的另一个BigInteger后的余数。

语法 :

public BigInteger remainder(BigInteger big)

参数： 该函数接受一个强制参数big，该参数指定了我们想要除以这个大整数对象的大整数对象。

返回： 该方法返回等于该BigInteger % big（作为参数传递的BigInteger）的BigInteger。

异常 该方法抛出一个算术异常 - 当big = 0时。

例子
输入: BigInteger1=321456, BigInteger2=31711
输出： 4346
解释： BigInteger1.remainder(BigInteger2)=4346。在321456和31711之间进行除法运算
剩余部分返回4346。

输入: BigInteger1=59185482345, BigInteger2=59185482345
输出： 0
解释： BigInteger1.remainder(BigInteger2)=0。
59185482345和59185482345之间的除法运算，返回0作为余数。

例1：下面的程序说明了BigInteger类的remainder()方法

// Java program to demonstrate remainder() method of BigInteger
  
import java.math.BigInteger;
  
public class GFG {
  
    public static void main(String[] args)
    {
  
        // Creating 2 BigInteger objects
        BigInteger b1, b2;
  
        b1 = new BigInteger("321456");
        b2 = new BigInteger("31711");
  
        // apply remainder() method
        BigInteger result = b1.remainder(b2);
  
        // print result
        System.out.println("Result of remainder "
                           + "operation between " + b1
                           + " and " + b2 + " equal to " + result);
    }
}

输出。

Result of remainder operation between 321456 and 31711 equal to 4346

例2：当两者的价值相等时。

// Java program to demonstrate remainder() method of BigInteger
  
import java.math.BigInteger;
  
public class GFG {
  
    public static void main(String[] args)
    {
  
        // Creating 2 BigInteger objects
        BigInteger b1, b2;
  
        b1 = new BigInteger("3515219485");
        b2 = new BigInteger("3515219485");
  
        // apply remainder() method
        BigInteger result = b1.remainder(b2);
  
        // print result
        System.out.println("Result of remainder "
                           + "operation between " + b1
                           + " and " + b2 + " equal to " + result);
    }
}

输出。

Result of remainder operation between 3515219485 and 3515219485 equal to 0

例3：当作为参数传递的BigInteger等于零时，程序显示异常。

// Java program to demonstrate remainder() method of BigInteger
  
import java.math.BigInteger;
  
public class GFG {
  
    public static void main(String[] args)
    {
  
        // Creating 2 BigInteger objects
        BigInteger b1, b2;
  
        b1 = new BigInteger("3515219485");
        b2 = new BigInteger("0");
  
        // apply remainder() method
        BigInteger result = b1.remainder(b2);
  
        // print result
        System.out.println("Result of remainder "+
                "operation between " + b1
                + " and " + b2 +
                " equal to " + result);
    }
}

输出：
