UnaryOpUGen apply a unary operation to the values of an input ugen

UnaryOpUGens are created as the result of a unary operator applied to a UGen. 

(SinOsc.ar(200).abs).dump;

(LFSaw.ar(200).sin).dump;

As in the examples given here, you don't usually need to instantiate UnaryOpUGen youself. 

Examples for unary operations on UGens are to be found in UGen's superclass AbstractFunction. They include: neg, abs, ceil, floor, frac, squared, cubed, sqrt, exp, log, log2, log10, sin, cos, scurve, distort

*new(selector, a) return a new instance that applies the operator (selector) to the ugen (a)

Examples

a = WhiteNoise.ar; // a WhiteNoise

b = a.squared; // a UnaryOpUGen.

b.operator; // squared

// sound example

{ var a = LFSaw.ar(300).range(0, 2pi); a.sin * 0.1 }.play;

// Plotting the "abs" unary operator (via the server):

{ SinOsc.ar(300).abs }.plot
