# numpy.absolute() in Python

numpy.absolute(arr, out = None, ufunc ‘absolute’) : This mathematical function helps user to calculate absolute value of each element. For complex input, a + ib, the absolute value is .

Parameters :

arr  : [array_like] Input array or object whose elements, we need to test.


Return :

An array with absolute value of each array.


Code #1 : Working

 # Python program explaining  # absolute () function     import numpy as np     arr1 = [1, -3, 15, -466]  print ("Absolute Value of arr1 : \n",                      np.absolute(arr1))     arr2 = [23 , -56]  print ("\nAbsolute Value of arr2 : \n",                          np.absolute(arr2))

Output :

Absolute Value of arr1 :
[  1   3  15 466]

Absolute Value of arr2 :
[23 56]


Code #2 : Working with complex numbers

 # Python program explaining  # absolute () function     import numpy as np     a = 4 + 3j print("Absolute(4 + 3j) : ",               np.absolute(a))     b = 16 + 13j print("\nAbsolute value(16 + 13j) : ",                          np.absolute(b))

Output :

Absolute(4 + 3j) :  5.0

Absolute value(16 + 13j) :  20.6155281281

Code #3: Graphical Representation of numpy.absolute()

 # Python program explaining  # absolute () function     import numpy as np  import matplotlib.pyplot as plt     a = np.linspace(start = -5, stop = 5,                  num = 6, endpoint = True)                     print("Graphical Representation : \n",                          np.absolute(a))     plt.title("blue : with absolute\nred : without absolute")  plt.plot(a, np.absolute(a))     plt.plot(a, a, color = 'red')  plt.show()

Output :
