numpy.isreal(array) : Test element-wise whether it is a real number or not(not infinity or not Not a Number) and return the result as a boolean array.
Parameters :
array : [array_like] Input array whose element we want to test
Return :
boolean array containing the result
Code 1 :
Python
# Python Program illustrating# numpy.isreal() method import numpy as geek print("Is Real : ", geek.isreal([1+1j, 0j]), "\n")print("Is Real : ", geek.isreal([1, 0]), "\n") |
Output :
Is Real : [False True] Is Real : [ True True]
Code 2 :
Python
# Python Program illustrating# numpy.isreal() method import numpy as geek # Returns True/False value for each element a = geek.arange(20).reshape(5, 4)print("Is Real : \n", geek.isreal(a), "\n") # Returns True/False value as ans # because we have mentioned dtype in the beginninga = geek.arange(20).reshape(5, 4).dtype = floatprint("\nIs Real : ", geek.isreal(a)) |
Output :
Is Real : [[ True True True True] [ True True True True] [ True True True True] [ True True True True] [ True True True True]] Is Real : True
