Class WideDecimal

java.lang.Object

java.lang.Number

com.devexperts.util.WideDecimal

All Implemented Interfaces:

Serializable, Comparable<WideDecimal>

public final class WideDecimal
extends Number
implements Comparable<WideDecimal>

The WideDecimal class contains a set of methods to work with floating-point numbers packed into long primitive type. Also, it can be used to wrap a single value in an object with interface like that of the Number class.
