@section{description}
|
||
|
|
|
||
|
|
UnaryOpUGens are created as the result of a unary operator applied to a link::Classes/UGen::.

::
|
||
|
|
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.
