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. -- This message was sent by Atlassian JIRA (v6.1.5#6160)
