The default value of enable_decimal256 is false. Setting it to true can
get more accurate results, but it will bring some performance loss.
+ When outputting decimal types, the decimal point is always followed by S
digits, even if the trailing digits are 0. For example, the number 123.456 of
type decimal(18, 6) will be output as 123.456000.

### Precision Deduction
DECIMAL has a very complex set of type inference rules. For different
expressions, different rules will be applied for precision inference.
