Gammapi_sub() Sub Gammapi_sub ( Ret As  Double, A As  Double, P As  Double, Optional Info As  Long  ) Inverse function of x for normalized incomplete gamma function P(a, x) (Subroutine version) Purpose Computes the inverse function of x for normalized incomplete gamma function P(a, x). Parameters [out] Ret Inverse function of x for normalized incomplete gamma function P(a, x). [in] A Argument a. (A > 0) [in] P Argument p. (0 <= P <= 1) [out] Info = 0: Successful exit. = -1: The argument A had an illegal value. (A <= 0) = -2: The argument P had an illegal value. (P < 0 or P > 1) = 1: Floating point range error.
