2. import numpy as np. x = float(“nan”) print(f”It’s np.isnan : { np.isnan(x) }”)OutputIt’s np.isnan : True.
3. import math. x = float(“nan”)

### Does NaN == NaN?

Yeah, a Not-A-Number is Not equal to itself. But unlike the case with undefined and null where comparing an undefined value to null is true but a hard check(===) of the same will give you a false value, NaN’s behavior is because of IEEE spec that all systems need to adhere to.
