Gamratio_sub() Sub Gamratio_sub ( Ret As  Double, A As  Double, B As  Double, Optional Info As  Long  ) Ratio of gamma functions Γ(a)/Γ(b) (Subroutine version) Purpose Computes the ratio of gamma functions Γ(a)/Γ(b). Parameters [out] Ret Ratio of gamma functions Γ(a)/Γ(b). [in] A Argument a. (A > 0) [in] B Argument b. (B > 0) [out] info = 0: Successful exit. = -1: The argument A had an illegal value. (A <= 0) = -2: The argument B had an illegal value. (B <= 0) = 1: Floating point range error. Reference boost/math/special_functions
