template< class T > complex<T> operator+( const complex<T>& val );	(1)
template< class T > complex<T> operator-( const complex<T>& val );	(2)

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, complex<T>(val)

2) negated argument, complex<T>(-val.real(), -val.imag())
