std::real(std::complex)

STD：：真实%28 std：：复合%29

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

返回复数的真实分量。z，即.z.real()...

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

真正的成分z...

另见

realaccesses the real part of the complex number (public member function)
imagreturns the imaginary component (function template)
