float('nan') results Nan (not a number). It is very easy but how can I check?

float('nan')

You can use math.isnan() which will return True if the variable is a NAN else False

Syntax-math.isnan(variable)

Syntax-

math.isnan(variable)

Alternatively, another way to test for NaN is comparing the number to itself.

def isNaN(num): return num != num

def isNaN(num):

return num != num
