> Contribute the Decimal128 high-performance decimal package developed by
> Microsoft to Hive. This was originally written for Microsoft PolyBase by
> Hideaki Kimura.
> This code is about 8X more efficient than Java BigDecimal for typical
> operations. It uses a finite (128 bit) precision and can handle up to
> decimal(38, X). It is also "mutable" so you can change the contents of an
> existing object. This helps reduce the cost of new() and garbage collection.
