DO NOT MERGE: QUICKSTEP-6: Decimal type
- This request adds the simple Decimal type which represents fixed
precision numbers.
- In practice, Decimal type is used with 2 arguments: precision and scale.
- Precision is the number of digits (base 10) that the type can show.
- Scale is the number of digits (base 10) after point.
- For example, Decimal(6, 2) can represent numbers from -9999.99 to
+9999.99.
- The type does not accept any precision and scale argument for now. It
takes default values 18 for precision and 2 for scale. It is chosen since
precision 18 is the limit that 64 bits can represent safely, and scale 2 is
what TPCH requires.
