Celli2_sub() Sub Celli2_sub ( Ret As  Double, K As  Double, Optional Info As  Long  ) Complete elliptic integral of the second kind E(k) (Subroutine version) Purpose Computes the Legendre form of complete elliptic integral of the second kind E(k). E(k) = E(π/2, k) where E(φ, k) is the incomplete elliptic integral of the second kind defined as follows. E(φ, k) = ∫ sqrt(1 - k^2(sin(t))^2) dt [0, φ] Parameters [out] Ret Complete elliptic integral of the second kind E(k). [in] K Argument k. (-1 <= K <= 1) [out] Info (Optional) = 0: Successful exit. = -1: The argument K had an illegal value. (K < -1 or K > 1) = 1: Floating point range error. Reference boost/math/special_functions
