Defined in header <complex>
template< class T > T imag( const complex<T>& z );	(1)
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().

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

Parameters

z

-

complex value

Return value

the imaginary component of z
