Perhaps a good idea is to implement the Gamma function additional
to factorial function. The gamma function as general function of
factorial accepts float/double values as argument and returns double.
Maybe a good idea too is to implement a set of standard statistical
functions for instance normal, poisson, binomial, etc to get less range
overflow while using statistical functions.
Perhaps when I'll have time, I will try to write a set of this functions
as contrib next year.
Thank you and regards ,
