  org.gcube.data.analysis.tabulardata.model.datatype.Numeric

All Implemented Interfaces:

Serializable, DataType

public class Numeric
extends Object
implements DataType

The type numeric can store numbers with up to 1000 digits of precision and perform calculations exactly. A Numeric is defined with a precision and a scale. The scale of a numeric is the count of decimal digits in the fractional part, to the right of the decimal point. The precision of a numeric is the total count of significant digits in the whole number, that is, the number of digits to both sides of the decimal point.
