What's the difference between constant and unmodifiable?
Constant
Definition:
(v. t.) Firm; solid; fixed; immovable; -- opposed to fluid.
(v. t.) Not liable, or given, to change; permanent; regular; continuous; continually recurring; steadfast; faithful; not fickle.
(v. t.) Remaining unchanged or invariable, as a quantity, force, law, etc.
(v. t.) Consistent; logical.
(n.) That which is not subject to change; that which is invariable.
(n.) A quantity that does not change its value; -- used in countradistinction to variable.
