The suitable preprocessor conditions could be by placing those declarations (of course with _Float32, _Float64, _Float128, _Float16 etc., cmath doesn't rely on stdfloat inclusion) right after the nextafter _Float32 etc. overloads. Anyway, if your template works properly even for the integers, even better.
