@... CGAMMA
  The Gamma function in the complex plane. Do LOAD(CGAMMA) to
use these functions. Functions Cgamma, Cgamma2, and LogCgamma2.
These functions evaluate the Gamma function over the complex plane
using the algorithm of Kuki, CACM algorithm 421. Calculations are
performed in single precision and the relative error is typically
around 1.0E7; evaluation at one point costs less than 1 msec. The
algorithm provides for an error estimate, but the Maxima
implementation currently does not use it.
Cgamma is the general function and may be called with a symbolic or
numeric argument. With symbolic arguments, it returns as is; with
real floating or rational arguments, it uses the Maxima Gamma
function; and for complex numeric arguments, it uses the Kuki
algorithm.
Cgamma2 of two arguments, real and imaginary, is for numeric arguments
only; LogCgamma2 is the same, but the loggamma function is
calculated. These two functions are somewhat more efficient.

@defun DIVSUM (n,k)
adds up all the factors of n raised to the kth power. If
only one argument is given then k is assumed to be 1.

The factorial function. FACTORIAL(X) = X! .
See also MINFACTORIAL and FACTCOMB. The factorial operator is !,
and the double factorial operator is !!.
