Detailed Description

Provides the interface for the woss::PDouble class.

Author

Federico Guerra

Provides the interface for the PDouble class. PDouble stands for PrecisionDouble: the value and the precision provided are used for arithmetic computations and comparisons. This class is not intented for inheritance: all containers used in WOSS are based on PDouble objects, not pointers to objects. Therefore, inheritance requires modification in other classes, to prevent object slicing when inserting in containers PDouble-derived objects instead of PDouble objects. Moreover, due to intensive use of PDouble objects, using heap-based pointers adds another layer of indirection, therefore adding an efficiency penalty.
