It takes three arguments. The first is @var{type} +which is a byte describing the type of floating point number to be created. +Possible values are @var{'f'} or @var{'s'} for single precision, @var{'d'} or +@var{'r'} for double precision and @var{'x'} or @var{'p'} for extended +precision. Either lower or upper case versions of these letters can be used. + +The second parameter is @var{litP} which is a pointer to a byte array where the +converted value should be stored. The third argument is @var{sizeP}, which is +a pointer to a integer that should be filled in with the number of +@var{LITTLENUM}s emitted into the byte array.
