More a case of "f(n) = 1/randFloat() does not have a well-defined limit as n goes to infinity", so it would be hard to say that it fits in ANY complexity class.

More a case of "f(n) = 1/randFloat() does not have a well-defined limit as n goes to infinity", so it would be hard to say that it fits in ANY complexity class. What is, however, clear is that its run-time does not depend on the size of the input. And technically, that means we can find a constant (infinity) that always... But, that is pretty unsatisfying.
