BigInteger shiftRight() Method in Java (original) (raw)

Last Updated : 11 Jul, 2025

prerequisite : BigInteger BasicsThe java.math.BigInteger.shiftRight(int n) method returns a BigInteger whose value is (this >> n). The shift distance, n, may be negative, in which case this method performs a left shift. The shiftRight() method will move each digit in a number's binary representation right by n times and the last bit in the direction of the shift is replaced by 0. This shiftRight() method Computes floor(this / 2^n).Syntax:

public BigInteger shiftRight(int n)

Parameter: The method takes one parameter n of integer type which refers to the shift distance in bits.Return Value: The method returns the BigInteger after shifting the bits to right by n times.Exceptions: The method might throws an ArithmeticException if the shift distance is an Integer.MIN_VALUE.Examples:

Input: BigInteger = 2300, n = 3 Output: 287 Explanation: Binary Representation of 2300 = 100011111100 Shift distance, n = 3. After shifting 100011111100 right 3 times, Binary Representation becomes 100011111 and Decimal equivalent of 100011111 is 287.

Input: BigInteger = 35000, n = 5 Output: 1093

Below program illustrates shiftRight(index) method of BigInteger:

Java `

// Program to demonstrate shiftRight() // method of BigInteger

import java.math.*;

public class GFG {

public static void main(String[] args)
{

    // Create BigInteger object
    BigInteger biginteger = new BigInteger("2300");

    // Create a int i for Shift Distance
    int i = 3;

    // Call shiftRight() method on bigInteger at index i
    // store the return value as BigInteger
    BigInteger changedvalue = biginteger.shiftRight(i);

    String result = "After applying shiftRight by Shift Distance " + i + 
    " on " + biginteger + " New Value is " + changedvalue;

    // Print result
    System.out.println(result);
}

}

`

Output:

After applying shiftRight by Shift Distance 3 on 2300 New Value is 287
