Example: The function f(x) = [x] increases at every x ∈ ℕ by 1.
The function NUF(x) increases at every x = unit fraction 1/n by 1. It
does not increase at 0 because 0 is not a unit fraction.
What exactly happens at those points?
The simplest action possible in mathematics: f --> f + 1
What you wrote above is a function associating a function to a function.
For instance [f -> f + 1](sin) = [x -> sin(x) + 1]
Definitely NOT what you intended. Try to write what you mean in proper
algebra (Hint: you'll notice you can't).
