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

Last Updated : 11 Jul, 2025

prerequisite : BigInteger BasicsThe java.math.BigInteger.abs() method returns absolute value of a BigInteger. By using this method one can find absolute value of any large size of numerical data stored as BigInteger.Syntax:

public BigInteger abs()

Parameters: The method does not take any parameters.Return Value: The method returns the absolute value of a BigInteger.Examples:

Input: -2300 Output: 2300 Explanation: Applying mathematical abs() operation on -2300, positive 2300 is obtained i.e |-2300| = 2300.

Input: -5482549 Output: 5482549

Below program illustrates abs() method of BigInteger:

Java `

// Below program illustrates the abs() method // of BigInteger

import java.math.*;

public class GFG {

public static void main(String[] args) {

    // Create BigInteger object
    BigInteger biginteger=new BigInteger("-2300");
    
    // abs() method on bigInteger to find the absolute value
    // of a BigInteger
    BigInteger absolutevalue= biginteger.abs();
        
    // Define result
    String result ="BigInteger "+biginteger+
        " and Absolute value is "+absolutevalue;
    // Print result 
    System.out.println(result);

}

}

`

Output:

BigInteger -2300 and Absolute value is 2300
