Pokrajac and Nikoli (see ibid., vol.43, no.12, p.2868, 1995) have correctly identified a mistake by Metzger (see ibid., vol.COM-35, no.4, p.396-402). The examples presented by Metzger were calculated correctly, but the carelessness in the formulation of the equation is regretted. It was intended to show the feasibility of the basic transformation, and not to give an exhaustive investigation of the numerical possibilities for executing the equation. Some more sophisticated ways for performing the evaluation are included.
