While the concept they represent is simple, constants, however, have some interesting properties that make them useful, especially when working with numeric values.

One of the most interesting properties of constants is that their literal representations can either be treated as typed or untyped values. Unlike variables, which are intrinsically bound to a type, constants can be stored as untyped values in memory space. Without that type constraint, numeric ...
