Read the actual regulations for your university first. Or ask someone who will know the regulations for your university and course (e.g. academic supervisor, assessment administrator etc) Often the award mark is the rounded whole number but different universities have different rules for how awards are classified so nobody can help without more information.
You haven't said anything about what grounds you would have for an appeal, but appeals would normally be after the exam boards as until then you don't actually have a result to appeal against.
