There is another notable distinction that is not recorded in ComplexRepresentations. Several implementations that are not able to represent mixed exactness in the general case are able to do so in one special case: when the imaginary part is exact 0. Examples of such implementations include Guile 2.0, Racket, and Ikarus.
