Class Decimal

java.lang.Object

org.apache.gravitino.rel.types.Decimal

public class Decimal
extends java.lang.Object

Used to represent a Types.DecimalType value in Apache Gravitino.

For Decimal, we expect the precision is equal to or larger than the scale, however, in BigDecimal, the digit count starts from the leftmost nonzero digit of the exact result. For example, the precision of 0.01 equals to 1 based on the definition, but the scale is 2. The expected precision should be 2.
