Hi all, The report occasionally mentions "an inexact complex number" or "an exact complex number". Does this imply that there's no such thing as a complex number of mixed exactness?
Gambit, for example, allows this: 1/2+0.5i Other Schemes I've looked at (not that many, though) return a normalised complex number with both real and imaginary parts converted to inexact. As far as I can see, this only has impact on the behavior of eqv?, which needs to check that the exactness of both parts match and then compare both parts with the regular "=" procedure. I'm not sure about the usefulness of this (but I'm not convinced it's useless, either) Am I missing anything?
