[sage-support] Re: Using factorial() in symbolic calculus

Sage does have the Gamma function implemented for real and complex arguments, but it does not seem able to treat it as a symbolic function which can be passed to maxima. Is that something which could be changed? sage: factorial(5) 120 sage: factorial(5) == gamma(6) True sage: gamma(2.3) 1.166711
