NAME

std::complex<T>::operator+(unary),operator-(unary) - std::complex<T>::operator+(unary),operator-(unary)

Synopsis

template< class T > (until C++20)
std::complex<T> operator+( const std::complex<T>& val );
template< class T > (since C++20)
constexpr std::complex<T> operator+( const std::complex<T>& val ); (1)
template< class T > (until C++20)
std::complex<T> operator-( const std::complex<T>& val ); (2)
template< class T > (since C++20)
constexpr std::complex<T> operator-( const std::complex<T>& val );

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())
