r = ift * -1i;
should do it.

Posted in reply to Walter Bright | Thxs for the reply Walter. But the cast(real) used to work...why exactly is the reason this doesn't now? I know you changed the implict conversion of imaginary floats so they do not work for a good reason, just unsure why the explict cast() has changed also. Thanks for your reply in advance.

Posted in reply to Don Clugston | Don thanks for pointing that out, but it has little use in templates I'm afraid...the place where I'm having my issue at the moment.
