@section{description}
UnaryOpUGens are created as the result of a unary operator applied to a link::Classes/UGen::.
@racketblock[
(SinOsc.ar(200).abs).dump;
(LFSaw.ar(200).sin).dump;
::
As in the examples given here, you don't usually need to instantiate UnaryOpUGen yourself.
The unary and binary operators are defined in link::Classes/UGen::'s superclass link::Classes/AbstractFunction::, which creates the
BinaryOpUGen as a result of the operation.
See link::Overviews/Operators:: for an overview of common operators.
