Summary
A data value in a computer corresponds to an object or mathematical value. There are many possibilities. See the topics and related topics for this group. (cbb 4/98)
Subtopic: value vs. reference
Quote: a value type is a bit sequence allocated on the stack with an implicit type; defines a representation and valid operations [»hamiJ2_2003]
Subtopic: negative value
Quote: Java non-references are values of primitive types without aliasing or sharing [»bacoDF10_2000] Quote: a reference type is an explicitly typed object allocated from the heap; unique identity and type handle
Subtopic: boxed value
Quote: use complementary numbers for subtraction [»compHU_1946]
Quote: any value type instance can be boxed and turned into a reference type instance; inherits from ValueType or Enum; no subtyping [»hamiJ2_2003] Quote: C# has a unified type system with boxed values; e.g., allows Stack to store elements of any type, including int
