Continued fractions with non-integer numerators
Journal of integer sequences, Tome 20 (2017) no. 1
Anselm and Weintraub investigated a generalization of classic continued fractions, where the "numerator" 1 is replaced by an arbitrary positive integer. Here, we generalize further to the case of an arbitrary real number $z \ge 1$. We focus mostly on the case where $z$ is rational but not an integer. Extensive attention is given to periodic expansions and expansions for $\sqrt n$, where we note similarities and differences between the case where $z$ is an integer and when $z$ is rational. When $z$ is not an integer, it need no longer be the case that $\sqrt n$ has a periodic expansion. We give several infinite families where periodic expansions of various types exist.
