Gamic() Function Gamic ( A As  Double, X As  Double, Optional Info As  Long  ) Complementary incomplete gamma function Γ(a, x) Purpose Computes the complementary incomplete gamma function. Γ(a, x) = ∫ t^(a-1)*exp(-t) dt [x, ∞] Returns Double Complementary incomplete gamma function Γ(a, x) Parameters [in] A Argument a. (A > 0 if X = 0) [in] X Argument x. (X >= 0) [out] Info (Optional) = 0: Successful exit. = -1: The argument A had an illegal value. (A <= 0 when X = 0) = -2: The argument X had an illegal value. (X < 0) = 1: Floating point range error.
