## The Python abs() function

The Python library consists of a large number of in-built functions that help in performing numerous operations. One of these functions is the `abs()`

function. The **Python **

is a built-in function that comes with the standard library of python and it returns the **abs()**__absolute value__ of a number that is passed as a parameter to this method. The absolute value of a number is the value without considering its sign i.e. the **non-negative value** of a number. For example, the absolute value of -35 is 35 and the absolute value of 35 is 35 as well since the sign is not considered in absolute value.

**Syntax of abs() method:**

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

abs(value)

**What values does Python abs() function works on (Parameter values)?**

`abs()`

function only accepts numeric values. The following are the numbers on which the abs() function works:- integers, e.g. 9, -9, etc.
- floating point numbers, e.g. 3.14, 6.67, etc.
- complex numbers, e.g. 2+5i, 7+9i, etc.

**Return Value of abs() function:**

`abs()`

method takes a single argument and returns its absolute value. If the argument passed is an integer it returns an integer value and if it is a float value, the return value is also a float. However, if a complex number is passed as a parameter, the function __returns the magnitude of the complex number__as a float value.

**Examples:**

**Passing an integer value:**

```
# Absolute value of integer
x = -95
print("Absolute value of -95 is", abs(x))
y = 30
print("Absolute value of 30 is", abs(y)
```

**Output:**

Absolute value of -95 is 95

Absolute value of 30 is 30

**Passing a float value:**

```
# Absolute value of float
x = -3.14
print("Absolute value of -3.14 is", abs(x))
y = 9.8
print("Absolute value of 9.8 is", abs(y)
```

**Output: **

Absolute value of -3.14 is 3.14

Absolute value of 9.8 is 9.8

**Passing a complex value:**

```
# Absolute value of complex number
# abs() method return magnitude of a complex number
x = 3+4j
print("Absolute value of 3+4j is", abs(x))
y = 7-5j
print("Absolute value of 7-5j is", abs(y))
```

**Output: **

****Absolute value of 3+4j is 5.0

Absolute value of 7-5j is 8.602325267042627

**Uses of abs():**

`abs()`

method is very useful in mathematical operations that require the absolute value of a certain parameter. Also, it can be used for finding the magnitude of a given complex number.
