Description

We want to provide an interface for floating point vectors (float4 & float8). This interface will make it convenient for many operations on a vector. 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 floating point values:

         setWithPossibleTruncate

         setSafeWithPossibleTruncate

         getValueAsDouble
