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 a specific number. In this section, we discuss how to use fabs function in Python Programming language with example.

The syntax of the fabs Function in Python Programming Language to find absolute values is

Math.fabs(number);

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

  • If the number argument is a positive or negative number, the fabs function returns the absolute value.
  • If the number argument is not a number, the fabs function returns TypeError.

Python fabs Function Example

The fabs Function allows you to find the absolute values of numeric values. In this fabs 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 used the fabs Function directly on both the Positive integer and negative integer. The following Python statements 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 Tuple and List items. If you observe the above screenshot, the Python fabs function is working perfectly on them and finding absolute values.

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 Math 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 the fabs Function on the String value, and it returns TypeError.

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