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

### See also

imag | returns the imaginary component (function template)
real | accesses the real part of the complex number (public member function)
