std::imag(std::complex)

STD：：imag%28 std：：Complex%29

Defined in header ​​
template< class T > T imag( const complex<T>& z (1)(until C++14)
template< class T > constexpr T imag( const complex<T>& z (1)(since C++14)
long double imag( long double z (2)(since C++11)
template< class DoubleOrInteger > double imag( DoubleOrInteger z (3)(since C++11)
float imag( float z (4)(since C++11)

返回复数的虚分量。z，即.z.imag()...

额外超载float，，，double，，，long double，以及所有整数类型，它们被视为零虚分量的复数。%28自C++11%29。

参数

z-complex value

返回值

假想成分z...

另见

imagaccesses the imaginary part of the complex number (public member function)
realreturns the real component (function template)
