Python Program for fabs() Function

In the previous article, we have discussed Python Program for copysign() Function
fabs() Function in Python:

The math. fabs() method returns a float containing the absolute value of a number.

The term absolute refers to a non-negative number. If the value has a negative sign, this removes it.

This method, unlike Python abs(), always converts the value to a float value.

Syntax:

math.fabs(x)

Parameters:

x: This is required. It is a number. If we try anything other than a number, we get a TypeError.

Return Value: It returns a float value which represents the absolute value of x.

Examples:

Example1:

Input:

Given list = [1, -2, -3, 4]
Given first number = 45
Given second number = -70

Output:

The absolute value of above given number 45  =  45.0
The absolute value of above given number -70  =  70.0
The absolute value of given list element gvnlst[2] =  3.0

Example2:

Input:

Given list = [86, 34, 20, 10]
Given first number = 90
Given second number = -40

Output:

The absolute value of above given number 90  =  90.0
The absolute value of above given number -40  =  40.0
The absolute value of given list element gvnlst[1] =  34.0

Method #1: Using Built-in Functions (Static Input)

Approach:

Import math module using the import keyword.
Give the list as static input and store it in a variable.
Give the number as static input and store it in another variable.
Apply math.fabs() function to the given number to get the absolute value of the given number as float and print it.
Similarly, do the same for the other number.
Apply math.fabs() function to the given list element and print it.
The Exit of Program.

Below is the implementation:

# Import math module using the import keyword.
import math
# Give the list as static input and store it in a variable.
gvn_lst = [1, -2, -3, 4]
# Give the number as static input and store it in another variable.
gvn_numb1 = 45
# Apply math.fabs() function to the given number to get the absolute value of
# the given number as float and print it.
print("The absolute value of above given number",
      gvn_numb1, " = ", math.fabs(gvn_numb1))
# similarly do the same for the other number.
gvn_numb2 = -70
print("The absolute value of above given number",
      gvn_numb2, " = ", math.fabs(gvn_numb2))
# Apply math.fabs() function to the given list element and print it.
print(
    "The absolute value of given list element gvnlst[2] = ", math.fabs(gvn_lst[2]))

Output:

The absolute value of above given number 45  =  45.0
The absolute value of above given number -70  =  70.0
The absolute value of given list element gvnlst[2] =  3.0

Method #2: Using Built-in Functions (User Input)

Approach:

Import math module using the import keyword.
Give the list as user input using list(),map(),input(),and split() functions.
Store it in a variable.
Give the number as user input using the int(input()) function and store it in a variable.
Apply math.fabs() function to the given first number to get the absolute value of the given number as float and print it.
Similarly, do the same for the other number.
Apply math.fabs() function to the given list element and print it.
The Exit of Program.

Below is the implementation:

# Import math module using the import keyword.
import math
# Give the list as user input using list(),map(),input(),and split() functions.
# Store it in a variable.
gvn_lst = list(map(float, input(
   'Enter some random List Elements separated by spaces = ').split()))
   
# Give the number as user input using the int(input()) function and store it in a variable.
gvn_numb1= int(input("Enter some random number = "))
# Apply math.fabs() function to the given first number to get the absolute value of
# the given number as float and print it.
print("The absolute value of above given number",
      gvn_numb1, " = ", math.fabs(gvn_numb1))
# similarly do the same for the other number.
gvn_numb2 = int(input("Enter some random number = "))
print("The absolute value of above given number",
      gvn_numb2, " = ", math.fabs(gvn_numb2))
# Apply math.fabs() function to the given list element and print it.
print(
    "The absolute value of given list element gvnlst[1] = ", math.fabs(gvn_lst[1]))

Output:

Enter some random List Elements separated by spaces = 86 34 20 10
Enter some random number = 90
The absolute value of above given number 90 = 90.0
Enter some random number = -40
The absolute value of above given number -40 = 40.0
The absolute value of given list element gvnlst[1] = 34.0
