# Python Abs() Function: For Absolute Value

## The objective of this Python post, you will see various Python examples that cover the following:

• What is abs() function?
• Python abs() function syntax and Parameters.
• Python abs() function examples.

## What is abc() function?

Python abs() is a standard builtin python function, which is used to returns the absolute value of the given number. If the number is complex, the abs() method returns its magnitude.

## Python absolute Syntax

Python abs() method syntax is the following.

```abs(n)
```

Here, n is the required parameter, and it is the number.

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

1. For integers – absolute integer value is returned
2. For floating numbers – floating absolute value is returned
3. For complex numbers – the magnitude of the number is returned

See the first example of python abs() function following:

```x = abs(-19.21)

print(x)
```

Output

`19.21`

## Python abs() function examples

### 1:Python abs() with complex number

```y = abs(18 + 21j)

print(y)
```

Output

` 27.65863337187866 `

### 2: Python abs() with different format numbers

```x = 19.21e1/2 # exponential
print(abs(x))

y = 0b1100 # binary
print(abs(y))

z = 0o11 # octal
print(abs(y))

print(abs(w))
```

Output

```86.05
12
12
15 ```

### 3: Python absolute value of list

Let’s see take an example, how to obtain the absolute number from python list.

Assume, we have one lists, it has looks like:

```inputList = [11, 2, -18, 50]
```

Also. use the map() and list() python function to convert it to the absolute value.

```inputList = [11, 2, -18, 50]
mappedList = map(abs, inputList)
print(list(mappedList))

```

Output

` [11, 2, 18, 50] `

### 4: write a program to find out the absolute value of an input number in python

• Use a python input() function in your python program that allows the user to enter any number.
• Convert the user inputted number into absolute numbers using the abs () function.
• End of python program, Print the result
```#program to find out absolute value of an input number in python

num = int(input(" Please Enter the number : "))

abs = abs(num)

print("The absolute value of given number is : ", abs)

```

Output

```Please Enter the number :  -5
The absolute value of given number is :  5 ```
