Nope. From what you say follows that Sage’s dilog(x) and Fricas’ dilog(1-x) are the *same mathematical object*. Therefore, the Fricas translation of Sage’s dilog(<something>) should be dilog(1-<something>). And *vice-versa* : the Sage’s translation of Fricas’ dilog(<something>) should be Sage’s dilog(1-<something>).
That's precisely what the FriCAS-SageMath interface currently does. Martin -- You received this message because you are subscribed to the Google Groups "sage-devel" group.
