```
public DecimalType(int precision,
                   int scale)
```
    Creates a decimal type with precision and scale.
    Examples:
    
    123.45 has precision 5, scale 2.
    12,345,000 has precision 5, scale -3.
    
    The largest value is 10 ^ (precision - scale). Hence the largest DECIMAL(5, -3) value is 10 ^ 8.
    Parameters:
    
    precision - Maximum number of decimal digits which a value of this type can have. Must be greater than zero. Use Integer.MAX_VALUE if the precision is unbounded.
    
    scale - Number of digits to the right of the decimal point.
