std::complex::real(3) C++ Standard Libary std::complex::real(3) NAME std::complex::real - std::complex::real Synopsis primary template complex<T> T real() const; (until C++14) constexpr T (since real() const; C++14) void real( T (until value ); C++20) constexpr void (since real( T value ); C++20) specialization complex<float> float real() (until const; C++11) constexpr float (since real() const; C++11) void real( float (until value ); C++20) constexpr void (since real( float C++20) value ); specialization complex<double> double real() (1) (until const; C++11) constexpr double (2) (since real() const; C++11) void real( (un- til double value ); (1) C++20) constexpr void (since real( double (2) C++20) value ); specialization complex<long (1) double> long double (2) (until real() const; C++11) constexpr long (since double real() C++11) const; (1) void real( long (until double value ); C++20) constexpr void (2) (since real( long C++20) double value ); Accesses the real part of the complex number. 1) Returns the real part. 2) Sets the real part to value. Parameters value - the value to set the real part to Return value 1) The real part. 2) (none) Notes In C++11, overload (1) in complex specializations used to be speci- fied without const qualifier. However, in C++11, a constexpr specifier used in a non- static member function implies const, and thus the behavior is as if const is specified.
