# Java.lang.StrictMath.abs() Method

## Description

The java.lang.StrictMath.abs(double a) method returns the absolute value of a double value. If the argument is not negative, the argument is returned. If the argument is negative, the negation of the argument is returned. It include some cases:

• If the argument is positive zero or negative zero, the result is positive zero.
• If the argument is infinite, the result is positive infinity.
• If the argument is NaN, the result is NaN.

## Declaration

Following is the declaration for java.lang.StrictMath.abs() method

```public static double abs(double a)
```

## Parameters

• a − This is the argument whose absolute value is to be determined.

## Return Value

This method returns the absolute value of a double value.

NA

## Example

The following example shows the usage of java.lang.StrictMath.abs() method.

```package com.tutorialspoint;

import java.lang.*;

public class StrictMathDemo {

public static void main(String[] args) {

double d1 = 1245.9 , d2 = -987.8;

// returns the absolute value of positive double value
double dAbsValue = StrictMath.abs(d1);
System.out.println("absolute value of " + d1 + " = " + dAbsValue);

// returns the absolute value of negative double value
dAbsValue = StrictMath.abs(d2);
System.out.println("absolute value of " + d2 + " = " + dAbsValue);
}
}
```

Let us compile and run the above program, this will produce the following result −

```absolute value of 1245.9 = 1245.9
absolute value of -987.8 = 987.8
```
