# Java – Find Absolute Value of Float – abs() Method with Examples

`java.lang.Math.abs()` method is used to find the absolute value of a float value in Java for the given input (`x` – parameter).
If the argument is not negative, the argument is returned. If the argument is negative, the negation of the argument is returned.

`abs()` method exists in `Math` class of `java.lang` package.
Since: JDK1.0

## Declaration of `abs()` Method

The declaration of `abs()` method is:

## Syntax of `abs()` Method

The syntax of `abs()` method in Java is:

Example

Output:
` 4876.1875 `
Example
By importing `java.lang` package the syntax of `abs()` method can be used as:

Output:
` 68.97 `

## Special Cases of `abs()` Method in Java

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.
Example

Output:
` 0.0 0.0 Infinity Infinity NaN `

## Parameters of `abs()` Method in Java

`x` – Where `x` is any valid float input value. This parameter is required.

## Error Handling

If the `x` parameter is not a number `abs()` method returns an `error`.
If there is no argument (`x` – input value) passes to the method, the compiler will produce an `error`.
Example

Output:
`Error`

## Return Value of `abs()` Method in Java

`abs()` method returns the absolute value of a float value for the given input (`x` – parameter).

## Java `abs()` Method Example 1

Output:
` absolute value of a Negative Value: 18.869 absolute value of a Positive Value: 27.78639 absolute value of Zero: 0.0 `

## Java `abs()` Method Example 2

Output:
` 3.4028235E38 1.4E-45 NaN 126.0 4.2867E-11 16.852 0.0 2.58 7.8856902E8 `
