    Python cmath.isnan() Method

    Python cmath.isnan() method in python is used to return a Boolean value(true or false) and to checks whether a value is nan (Not a Number), or not. If the value is Nan returns True otherwise False

    Syntax:
    cmath.isnan(x)

    Parameter Values

    Parameter Description
    X It is a Required parameter used to check for NaN value
    Here is an Example of Python cmath.isnan() Method: 
    
import cmath
print (cmath.isnan(15 + float('nan')))
print (cmath.isnan(5 + 4j))
    Output:
    True
    False
    Example 2: 
    
import cmath
print (cmath.isnan(8 + float('nan')))
print (cmath.isnan(2 + 7j))
    Output:
    True
    False
