You should be able to handle this a few lines above, changing

	  /* Check for a hex constant.  */
	  for (s = input_line_pointer; hex_p (*s); s++)
	    ;
	  if (*s == 'h' || *s == 'H')
to
	  /* Check for a hex constant or floating point number.  */
	  for (s = input_line_pointer; hex_p (*s); s++)
	    ;
	  if (*s == 'h' || *s == 'H' || *input_line_pointer == '.')

This is careless.  What about case '!' and case '~'?  Please fix
your formatting too.
