Based on our previous work, with the aid of the numerical method, the phase pro bability distributions of Roy-type even and odd nonlinear coherent states are in vestigated. It is shown that the distributions for the states are rather different, and unlike the case of ordinary even and odd coherent states the Pegg-Barnett distribution clearly reflects the different characters of quantum interference in the case of Roy-type even and odd nonlinear coherent states.
