> Implement the DECIMAL data type, and test for all built-in operators.
> Do it using shifted integer values (or long, or short, depending on the required precision). For example, to represent 1234.56 as a DECIMAL(10, 2) we would use a 123456L (a {{long}} value because signed 10^10 requires 34.2 bits) and divide by 100 (2^10) on the way out.
> In {{SqlOperatorBaseTest}}, convert {{public static final boolean DECIMAL = false}} to {{true}}, and fix the 9 tests where that constant is used.
