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.
