starteted implement float into sprintf, snprintf and alot other printf api. this is more like a start how to implement it. This commit is more market for me. so I do not forget where string functions of *printf api (the main api functions) are. One more thing if u change on sprintf.c same change must be done in swprintf.c or changes into swprintf.c same changes must be done in swprintf.c, other wise the efect of bugfix or change will not be excutected in reactos, for u do not know if program pic the ansi or unicode version.
