Syntax
y = + x

Purpose
Performs the unary plus operation (the result y is equal to the operand x ).

x
The operand x has one of the following prototypes       const AD<Base>               &x      const VecAD<Base>::reference &x 
y
The result y has type       AD<Base> y  It is equal to the operand x .

Operation Sequence
This is an AD of Base atomic operation and hence is part of the current AD of Base operation sequence .

Derivative
If $f$ is a Base function , $$\D{[ + f(x) ]}{x} = \D{f(x)}{x}$$

Example
The file unary_plus.cpp contains an example and test of this operation.
