Gopal Vijayaraghavan commented on HIVE-22315:
---------------------------------------------
{code}
Row 1 typeName1 decimal(12,2) typeName2 decimal(12,2) outputTypeName
decimal(16,6) DIVIDE VECTOR_EXPRESSION COLUMN_SCALAR result -0.005425
(HiveDecimalWritable) does not match row-mode expected result -0.005426
(HiveDecimalWritable) row values [3.95] scalar2 -728
{code}
Running it in bc
{code}
scale=6
3.95/-728
-.005425
3.95/-728
-.0054258
{code}
so this is a rounding issue.
