Hi, obviously exports Algebra the functions leftRecip and rightRecip. But the only place where these functions are implemented is in ncalg.spad.
(109) -> Fraction Integer has Algebra Integer (109) true Type: Boolean (110) -> x: Fraction Integer := 2/3 2 (110) - 3 Type: Fraction(Integer) (111) -> leftRecip x Internal Error The function leftRecip with signature hashcode is missing from domain Fraction(Integer) But this works. (111) -> recip x 3 (111) - 2 Type: Union(Fraction(Integer),...) Ralf -- You received this message because you are subscribed to the Google Groups "FriCAS - computer algebra system" group.
