Purely monetary factors are considered to be as much symptoms as causes, albeit symptoms with aggravating effects that should not be completely neglected.

`` Purely from the business man's standpoint and without regard to the lawyer's view '', commented a trade journal, `` the matter of patents in the automobile and accessory trade is developing some phases and results that challenge thought as to how far patents are to become weapons of warfare in business, instead of simple beneficient protection devices for encouraging inventive creation ''.

Purely electronic sound production can be achieved using devices such as the Theremin, sound synthesizer, and computer.

Purely mechanical thermostats are used to regulate dampers in some rooftop turbine vents, reducing building heat loss in cool or cold periods.

: Purely horizontal thinking is known as daydreaming, fantasy, mysticism.

: Purely vertical thinking is the classic method for problem solving: from the given data step by step working out the solution.

Purely inseparable extensions do occur naturally ; for example, they occur in algebraic geometry over fields of prime characteristic.

* If M is some set and S denotes the set of all functions from M to M, then the operation of functional composition on S is associative:

In C, all executable code is contained within subroutines, which are called " functions " ( although not in the strict sense of functional programming ).

In mathematics and, in particular, functional analysis, convolution is a mathematical operation on two functions f and g, producing a third function that is typically viewed as a modified version of one of the original functions, giving the area overlap between the two functions as a function of the amount that one of the original functions is translated.

* A functional equation is an equation in which the unknowns are functions rather than simple quantities.

In computer science, functional programming is a programming paradigm that treats computation as the evaluation of mathematical functions and avoids state and mutable data.

The historical roots of functional analysis lie in the study of spaces of functions and the formulation of properties of transformations of functions such as the Fourier transform as transformations defining continuous, unitary etc.
