Don't have that manual at hand, but I think that very much depends on the
compiler and/or the runtime architecture. I can assure you my (old, ugly,
buggy, horrible, non-standard, fp-less, whatever) compiler and
architecture do not make such a conversion. If a parameter is a float,
it's passed in one register (or memory slot), if it's a double, it takes
two registers/slots.

And if there isn't any particular reason beyond my sight why there has to
be a double in there, I would keep it consistent and make it a float.
Might save you (or someone else) time in the future.
