Update of /cvsroot/maxima/maxima/doc/info In directory sc8prcvs1.sourceforge.net:/tmp/cvsserv17402 Modified Files: Number.texi Log Message: Strike out description of unimplemented functions cgamma and cgamma2. "grep i cgamma" in src and share yields nothing except some comments. Slight revision of description of factorial; point reader to "!".

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  @... CGAMMA2   See CGAMMA.  @... defun  @defun DIVSUM (n,k) adds up all the factors of n raised to the kth power.
