The data type representing java.math.BigDecimal values. A Decimal that must have fixed precision (the maximum number of digits) and scale (the number of digits on right side of dot).

The precision can be up to 38, scale can also be up to 38 (less or equal to precision).

The default precision and scale is (10, 0).

Please use DataTypes.createDecimalType() to create a specific instance.
