Hi, I'm looking for a reviewer for this pull request: https://github.com/apache/trafodion/pull/1831
The associated JIRA is https://issues.apache.org/jira/browse/TRAFODION-3300 This is a change to how the ROUND function is evaluated for Big Num data types (that is, columns of type NUMERIC(n,m) where n > 18). Formerly, the Binder would rewrite this as a rather complicated expression in other functions. Unfortunately this rewrite was subject to overflows for the largest Big Num data types. The pull request adds an explicit Big Num ROUND operator to the expression evaluator which does not suffer from these overflows. Thanks, Dave
