NumPy: Calculate the absolute value element-wise

NumPy Mathematics: Exercise-7 with Solution

Write a NumPy program to calculate the absolute value element-wise.

Sample Solution:

Python Code:

# Importing the NumPy library
import numpy as np

# Creating an array with floating-point numbers
x = np.array([-10.2, 122.2, .20])

# Displaying the original array
print("Original array:")
print(x)

# Calculating the element-wise absolute value and displaying the result
print("Element-wise absolute value:")
print(np.absolute(x))

Sample Output:

Original array:                                                        
[ -10.2  122.2    0.2]                                                 
Element-wise absolute value:                                           
[  10.2  122.2    0.2]

Explanation:

In the above code:

x = np.array([-10.2, 122.2, .20]) – This line creates an array with three elements: -10.2, 122.2, and .20.

np.absolute(x) – This line calculates the absolute value of each element in x.

Finally, the result printed by print(np.absolute(x)) will be [10.2, 122.2, .2].
