Does the following help? The idea is that you specify the type so that the result is not Expression(Float) (and must later be converted to (Double)Float, but rather an element of DoubleFloat. Ralf F ==> DoubleFloat C0(S:F,r:F,T:F, K:F,s:F):F==((S*erf(((2*log((S/K))+T*s^2+2*T*r)/(2*s*sqrt(2)*sqrt(T))))-K*%e^((-T*r))*erf(((2*log((S/K))-T*s^2+2*T*r)/(2*s*sqrt(2)*sqrt(T))))-K*%e^((-T*r))+S)/2) C(K:F, s:F):F==C0(10.0, 0.05, 0.8, K, s) CC(s:F):F==C(11.0, s) draw(CC, 2.0..3.0) -- You received this message because you are subscribed to the Google Groups "FriCAS - computer algebra system" group.
