The minimal example is this: (4) -> x := sqrt(-1)::EXPR INT
┌───┐ (4) \│- 1 Type: Expression(Integer) (5) -> x::InputForm (5) (^ - 1 (/ 1 2)) Type: InputForm (6) -> unparse(x::InputForm) (6) "-1^(1/2)" Type: String (7) -> parse(unparse(x::INFORM))$INFORM (7) (- (^ 1 (/ 1 2))) Type: InputForm ============================ First, the correct answer of "unparse(x::InputForm)" should be "(-1)^(1/2)". Second, should "x::InputForm" return '(^ - 1 (/ 1 2))' or '(^ (- 1) (/ 1 2))', op.spad#L586 is related: https://github.com/fricas/fricas/blob/51888b33b333931fc06bd020105c03cb991c043d/src/algebra/op.spad#L586 -- You received this message because you are subscribed to the Google Groups "FriCAS - computer algebra system" group.
