Gammaqia() Function Gammaqia ( X As  Double, Q As  Double, Optional Info As  Long  ) Inverse function of a for normalized complementary incomplete gamma function Q(a, x) Purpose Computes the inverse function of a for normalized complementary incomplete gamma function Q(a, x). Returns Double Inverse function of a for normalized complementary incomplete gamma function Q(a, x). Parameters [in] X Argument x. (X > 0) [in] Q Argument q. (0 <= Q <= 1) [out] Info = 0: Successful exit. = -1: The argument X had an illegal value. (X <= 0) = -2: The argument Q had an illegal value. (Q < 0 or Q > 1) = 1: Floating point range error.
