• 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
```
