BigInteger remainder() Method in Java
The java.math.BigInteger.remainder(BigInteger big) method returns a BigInteger whose value is equal to (this BigInteger % big(BigInteger passed as parameter)).The remainder operation finds the remainder after division of this BigInteger by another BigInteger passed as parameter.
Syntax:
public BigInteger remainder(BigInteger big)
Parameter: The function accepts a single mandatory parameter big which specifies the BigInteger Object by which we want to divide this bigInteger object.
Returns: The method returns the BigInteger which is equal to this BigInteger % big(BigInteger passed as parameter).
ExceptionThe method throws an ArithmeticException – when big = 0
Examples:
Input: BigInteger1=321456, BigInteger2=31711
Output: 4346
Explanation: BigInteger1.remainder(BigInteger2)=4346. The divide operation
between 321456 and 31711 returns 4346 as remainder.
Input: BigInteger1=59185482345, BigInteger2=59185482345
Output: 0
Explanation: BigInteger1.remainder(BigInteger2)=0. The divide operation between
59185482345 and 59185482345 returns 0 as remainder.
Example 1: Below programs illustrate remainder() method of BigInteger class
import java.math.BigInteger;
public class GFG {
public static void main(String[] args)
{
BigInteger b1, b2;
b1 = new BigInteger( "321456" );
b2 = new BigInteger( "31711" );
BigInteger result = b1.remainder(b2);
System.out.println( "Result of remainder "
+ "operation between " + b1
+ " and " + b2 + " equal to " + result);
}
}
|
Output:
Result of remainder operation between 321456 and 31711 equal to 4346
Example 2: when both are equal in value.
import java.math.BigInteger;
public class GFG {
public static void main(String[] args)
{
BigInteger b1, b2;
b1 = new BigInteger( "3515219485" );
b2 = new BigInteger( "3515219485" );
BigInteger result = b1.remainder(b2);
System.out.println( "Result of remainder "
+ "operation between " + b1
+ " and " + b2 + " equal to " + result);
}
}
|
Output:
Result of remainder operation between 3515219485 and 3515219485 equal to 0
Example 3: program showing exception when BigInteger passed as parameter is equal to zero.
import java.math.BigInteger;
public class GFG {
public static void main(String[] args)
{
BigInteger b1, b2;
b1 = new BigInteger( "3515219485" );
b2 = new BigInteger( "0" );
BigInteger result = b1.remainder(b2);
System.out.println( "Result of remainder " +
"operation between " + b1
+ " and " + b2 +
" equal to " + result);
}
}

Output:
Exception in thread "main" java.lang.ArithmeticException: BigInteger divide by zero
