Python FABS

by

The Python FABS function is one of the Python Math function which returns the absolute value ((Positive value) of the specified expression or an individual number.

In this article we will show you, How to use FABS() function in Python Programming language with example.

Syntax of a Python FABS Function

The basic syntax of the FABS Function in Python Programming Language is as shown below:

Math.fabs(number);

Number: It can be a number or a valid numerical expression for which you want to find absolute value.

  • If the number argument is positive or negative number, fabs() function will return the absolute value.
  • If the number argument is not a number, fabs() function will return TypeError.

Python FABS Function Example

The Python FABS Function allows you to find the absolute values of a numeric values. In this example, We are going to find the python absolute values of different data types and display the output

# Python Absolute Value Example

import math

Tup = (1, 2, 3, -4 , 5) # Tuple Declaration
Lis = [-1, 2, -3.5, -4 , 5] # List Declaration

print('Absolute value of Positive Number = %.2f' %math.fabs(10))
print('Absolute value of Negative Number = %.2f' %math.fabs(-15))

print('Absolute value of Tuple Item = %.2f' %math.fabs(Tup[3]))
print('Absolute value of List Item = %.2f' %math.fabs(Lis[2]))

print('Absolute value of Multiple Number = %.2f' %math.fabs(10 + 20 - 40))
print('Absolute value of String Number = ', math.fabs('Hello'))

OUTPUT

Python FABS Function

ANALYSIS

First, We declared Python List and Tuple with some random values. Next, We used the FABS() Function directly on both the Positive integer and negative integer. Following statements will find the corresponding absolute values.

print('Absolute value of Positive Number = %.2f' %math.fabs(10))
print('Absolute value of Negative Number = %.2f' %math.fabs(-15))

Next, We used the FABS() Function on Python Tuple and List items. If you observe the above screenshot, FAbs() function is working perfectly on them.

print('Absolute value of Tuple Item = %.2f' %math.fabs(Tup[3]))
print('Absolute value of List Item = %.2f' %math.fabs(Lis[2]))

Next, We used the FABS() Function directly on multiple values.

print('Absolute value of Multiple Number = %.2f' %math.fabs(10 + 20 - 40))

It means,

FABS(10 + 20 – 40)

FABS (-10) = 10

Within the last statement, We tried FABS() Function on String value. As we said before, this will return TypeError as output

print('Absolute value of String Number = ', math.fabs('Hello'))
