       C++20)

	  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 std::complex specializations used to be
       specified 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.

	  Defect reports

	  The following	behavior-changing defect reports were applied retroac-
       tively to
	  previously published C++ standards.

	    DR	  Applied to	    Behavior as	published	       Correct
       behavior
