BigInteger shiftRight() Method in Java

Last Updated : 11 Jul, 2025

The

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

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
