Constant \Con"stant\ (k[o^]n"stant), a. [L. onstans, -antis, p.
pr. of constare to stand firm, to be consistent; con- stare
to stand: cf. F. constant. See {Stand} and cf. {Cost}, v. t.]
1. Firm; solid; fixed; immovable; -- opposed to {fluid}.
[Obs.]
[1913 Webster]

If . . . you mix them, you may turn these two fluid
liquors into a constant body. --Boyle.
[1913 Webster]

2. Not liable, or given, to change; permanent; regular;
continuous; continually recurring; steadfast; faithful;
not fickle. Opposite of {changeable} and {variable}.
[1913 Webster]

constant friends. --Sir P.
Sidney.

Syn: Fixed; steadfast; unchanging; permanent; unalterable;
immutable; invariable; perpetual; continual; resolute;
firm; unshaken; determined.

Usage: {Constant}, {Continual}, {Perpetual}. These words are
sometimes used in an absolute and sometimes in a
qualified sense. Constant denotes, in its absolute
sense, unchangeably fixed; as, a constant mind or
purpose. In its qualified sense, it marks something as
a "standing" fact or occurence; as, liable to constant
interruptions; constantly called for. Continual, in
its absolute sense, coincides with continuous. See
{Continuous}. In its qualified sense, it describes a
thing as occuring in steady and rapid succession; as,
a round of continual calls; continually changing.
Perpetual denotes, in its absolute sense, what
literally never ceases or comes to an end; as,
perpetual motion. In its qualified sense, it is used
hyperbolically, and denotes that which rarely ceases;
as, perpetual disturbance; perpetual noise; perpetual
intermeddling.
[1913 Webster]

[1913 Webster]

3. (Astron.) A number whose value, when ascertained (as by
observation) and substituted in a general mathematical
formula expressing an astronomical law, completely
determines that law and enables predictions to be made of
its effect in particular cases.
[Webster 1913 Suppl.]

4. (Physics) A number expressing some property or condition
of a substance or of an instrument of precision; as, the
dielectric constant of quartz; the collimation constant of
a transit instrument.
[Webster 1913 Suppl.]

5. (Computers) a data structure that does not change during
the course of execution of a program. It may be a number,
a string, or a more complex data structure; -- contrasted
with {variable}.
[PJC]
