cMath module contains a number of functions which is used for mathematical operations for complex numbers. The cmath.nan Constant is used to get the floating-point nan (Not a Number).
Syntax: cmath.nan
Returns: Return the floating-point nan value.
Below examples illustrate the use of above function:
Example #1 :
Python3
# Python code to implement # the cmath.nan constant # importing "cmath" # for mathematical operations import cmath # Print the value of nan val = cmath.nan print(val) |
Output:
nan
Example #2:
Python3
# Python code to implement # the cmath.nan constant # importing "cmath" # for mathematical operations import cmath # use of cmath.nan val = cmath.isnan(cmath.nan) print(val) |
Output:
True
