Ashutosh Chauhan commented on HIVE-14582:
-----------------------------------------
Patch looks good. Any reason you restricted scale argument to be constant? Your
evaluate method supports it, but you throw exception for non-constants in
initialize(). Date version already supports it, so we should consider
supporting it for numerics too. Will enable queries like:
create table t1(c double, d int); select trunc (c,d) from t1;
> Add trunc(numeric) udf
