DESCRIPTION
Calculate the minimum and maximum legal bounds for X in gamma(X). XMIN and XMAX are not the only bounds, but they are the only non- trivial ones to calculate. Output Arguments -- XMIN double precision minimum legal value of X in gamma(X). Any smaller value of X might result in underflow. XMAX double precision maximum legal value of X in gamma(X). Any larger value of X might cause overflow.
