The official release of JADE’s new version is scheduled for January 18 2004. It is a major release (V6.0) with the following improvements regarding quantities: - Support for exact quantities. Operations on exact quantities typically result in exact quantities (but not always e.g. squareRoot(2)). A new method isExact() indicates if a quantity is exact or an approximation. - Internal representation of quantities using integer mantissa and decimal exponents to ensure exact mapping between a quantity and its decimal representation) - New QuantityFormat class with support for the ± symbol (e.g. 1.2 ± 0.001 kg). - Finally Quantity implements the new (V6.0) interface Recyclable (intermediate/temporary objects can be reused without incurring the cost of memory allocation, object initialization and potential garbage collection).
