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 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.
