Defined in header <complex>

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 DoubleOrIngeter > double imag( DoubleOrInteger z );	(3)	(since C++11)
float imag( float z );	(4)	(since C++11)

Returns the imaginary component of the complex number z, i.e. z.imag().

Additional overloads are provided for float, double, long double, and all integer types, which are treated as complex numbers with zero imaginary component.(since C++11)

Parameters

z

-

complex value

Return value

the imaginary component of z
