Implements the analogs of the unary arithmetic operators for complex numbers.

1) Returns the value of its argument
2) Negates the argument

Parameters

val - the complex number argument

Return value

1) a copy of the argument, std:: complex < T > ( val )
2) negated argument, std:: complex < T > ( - val. real ( ) , - val. imag ( ) )
