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())
