The `abs()` function in Python returns the absolute value of a given number, which means the `abs()` method removes the negative sign of a number.

If the given number is complex, then the `abs()` function will return its magnitude.

## abs() Syntax

The syntax of `abs()` method is

abs(number)

## abs() Parameters

The `abs()` function takes a single argument, a number whose absolute value is to be returned. The number can be

• integer
• floating-point number
• complex number

## abs() Return Value

`abs()` method returns an absolute value of a given number.

• For integers – absolute integer value is returned
• For floating numbers – absolute floating-point value is returned
• For complex numbers – the magnitude of the number is returned

## What does the abs() function do in Python?

The `abs()` function will turn any negative number into positive, the absolute value of a negative number is multiplied by (-1) and returns the positive number, and the absolute value of a positive number is the number itself.

## Example 1: Get absolute value of a number in Python

In this example, we will pass an integer, float into the `abs()` function, and returns the absolute value.

``````# Python code to illustrate abs() built-in function

# integer number
integer = -10
print('Absolute value of -10 is:', abs(integer))

# positive integer number
positive_integer =20
print('Absolute value of 20 is:', abs(positive_integer))

# floating point number
floating = -33.33
print('Absolute value of -33.33 is:', abs(floating))
``````

Output

``````Absolute value of -10 is: 10
Absolute value of 20 is: 20
Absolute value of -33.33 is: 33.33
Absolute value of 3-4j is: 5.0``````

## Example 2: Get the magnitude of a complex number

In this example, we will pass a complex number into the `abs()` function and returns the absolute value.

``````# Python code to illustrate abs() built-in function

# complex number
complex=(3-4j)
print('Absolute value of 3-4j is:', abs(complex))``````

Output

``Absolute value of 3-4j is: 5.0``
