DecimalType
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. UseInteger.MAX_VALUE
if the precision is unbounded.scale
- Number of digits to the right of the decimal point.
