I don't think it fails in the same way as x^(1/3). S3 is a complex expression, although its value is always real, when computing in float number, there's a small imaginary part. The right thing to do is to give "draw" a real expression, such as "real(S3)", but there's no "real" for EXPR FLOAT (is that a bug?), convert it to EXPR FRAC INT first works: draw(real(S3::EXPR FRAC INT),t=0..100) -- You received this message because you are subscribed to the Google Groups "FriCAS - computer algebra system" group.
