I wonder whether this formula works also if we dont take the limit but directly put:

where of course we can again replace

where we can compute by regular iteration because it has a fixed point at (though not with Zdun's formula as his formula is only valid for while ).

In your equations, what does mean? And what does mean? I assume this is the mathematical shorthand for iterating "n" times. I'm going to have to get some education in higher mathematics .

What does mean? Is it restricted to values of x<e? And doesn't that limit the usefulness of the equation?
