The class scalar is a subclass of the class class, and the parent of all the simple numeric classes float , integer and unsignedinteger . An important characteristic of the scalar objects is that they have their data stored directly in the "car" part of their wwlisp cell, either as a 64 bits float, a 64 bits integer or a 64 bits unsigned integer. This is not the case with other classes, where the "car" can be actually a pointer to something else. |
