Resolution: Won't Fix
> [Java] Provide an interface for numeric vectors

> We want to provide an interface for all vectors with numeric types (small
> int, float4, float8, etc). This interface will make it convenient for many
> operations on a vector, like average, sum, variance, etc. With this
> interface, the client code will be greatly simplified, with many
> branches/switch removed.
>
> The design is similar to BaseIntVector (the interface for all integer
> vectors). We provide 3 methods for setting & getting numeric values:
> setWithPossibleRounding
> setSafeWithPossibleRounding
> getValueAsDouble
