# Swift Double abs()

In this tutorial, we will learn about the Swift Double abs() method with the help of examples.

The `abs()` method returns the absolute value of the given value.

### Example

``````var value = -20

// find absolute value of -20
var absoluteNumber = abs(value)

print(absoluteNumber)

// Output: 20``````

## abs() Syntax

The syntax of the `abs()` method is:

``abs(num)``

## abs() Parameters

The `abs()` method takes one parameter

• num - a signed number

## abs() Return Values

The `abs()` method returns the absolute value of num.

## Example: Swift Double abs()

``````var value1 = -20

// find absolute value of -20
var result1 = abs(value1)
print("Absolute value of -20 is:", result1)

var value2 = -33.33

// find absolute value of -33.33
var result2 = abs(value2)
print("Absolute value of -33.33 is:", result2)``````

Output

```Absolute value of -20 is: 20
Absolute value of -20 is: 33.33```

Here, we have used the `abs()` method to find the absolute value of the given numbers: value1 and value2.
