Python | Numpy ndarray.imag()

0 0 1 minute read

With the help of Numpy ndarray.imag() method, we can find the imaginary values in an imaginary expressions by just using ndarray.imag() method. Remember resulting data type for the imaginary value is ‘float64’.

Syntax : ndarray.imag()

Return : Array of imaginary values having dtype ‘float64’

Example #1 :
In this example we can see that we get the array of imaginary values using ndarray.imag() method and we are also trying to print the dtype of those imag values.

# import the important module in python 
import numpy as np 
          
# make an array with numpy 
gfg = np.array([1 + 2j, 2 + 3j]) 
          
# applying ndarray.imag() method 
zambiatek = np.imag(gfg) 
    
print(zambiatek, end ='\n\n') 
print(np.imag(zambiatek).dtype) 

Output:

[ 2.  3.]

float64

Example #2 :

# import the important module in python 
import numpy as np 
          
# make an array with numpy 
gfg = np.array([1 + 2j, 2 + 3j]) 
gfg = np.sqrt(gfg) 
          
# applying ndarray.imag() method 
zambiatek = np.imag(gfg) 
    
print(zambiatek, end ='\n\n') 
print(np.imag(zambiatek).dtype)
