However, as Gerald Smith so excellently points out, in each neighborhood of any negative rational value of n, no matter how small, there are some rational numbers with even denominators and some rational numbers with odd denominators

Guys, please keep in mind that exponentials of negative bases are not really functions.  They give a mix of real and multivalued complex results. You cannot treat  x^(1/3) as a synonym for cuberoot (x) if x,0. The latter is a well defined function and the former is not.  Perhaps this might be a
