std::complex::imag(3) C++ Standard Libary std::complex::imag(3) NAME std::complex::imag - std::complex::imag Synopsis primary template complex<T> T imag() const; (until C++14) constexpr T (since imag() const; C++14) void imag( T (until value ); C++20) constexpr void (since imag( T value ); C++20) specialization complex<float> float imag() (until const; C++11) constexpr float (since imag() const; C++11) void imag( float (until value ); C++20) constexpr void (since imag( float C++20) value ); specialization complex<double> double imag() (1) (until const; C++11) constexpr double (2) (since imag() const; C++11) void imag( (un- til double value ); (1) C++20) constexpr void (since imag( double (2) C++20) value ); specialization complex<long (1) double> long double (2) (until imag() const; C++11) constexpr long (since double imag() C++11) const; (1) void imag( long (until double value ); C++20) constexpr void (2) (since imag( long C++20) double value ); Accesses the imaginary part of the complex number. 1) Returns the imaginary part. 2) Sets the imaginary part to value. Parameters value - the value to set the imaginary part to Return value 1) The imaginary part of *this. 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.
