Proposed fix (work in progress)

Here is a proposed patch which fixes the rotate return type by converting both
arguments to the same type before calling ROTATE.  Although, on relfection, it
is probably better to convert the return result prior to assigning it to the
temporary variable.  I'll tidy this up and retest.
