Apparently it does when the imaginary part is exact zero.
If you doubt this, evaluate the following expression:

  (let ((x 2.0))
    (and (complex? x)
         (inexact? (real-part x))
         (exact?   (imag-part x))))

The results you reported for my tests indicate that you handle those
cases correctly.  The last three tests check for that.
