33.14.15
Originally the function was presented with argument given by a positive integer . It has now been clarified to be valid for argument given by a positive real number .
The condition for (1.2.2), (1.2.4), and (1.2.5) was corrected. These equations are true only if is a positive integer. Previously was allowed to be zero.
