  • Last Updated : 20 May, 2019

prerequisite : BigInteger Basics

The 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:




// 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
