Review comment:
Sorry, i am not sure i got it right.
Actually we test `RoundCeil` and `RoundFloor` directly for positive `scale`
on big decimal, i can add long and double in that case, if you prefer. But we
can't test `RoundCeil` and `RoundFloor` directly for negative `scale` because
the casting to `Long` for negative scale happens one step before.
May be if put the casting in the `RoundCeil` and `RoundFloor` objects and
let the `ExpressionBuilder` call these objects like it was before, we can able
to test `RoundCeil` and `RoundFloor` directly for both negative and positive
`scale`. What do you say ?
