The values of the "result" variables in these functions are always integers; using a float8 variable accomplishes nothing except to incur useless conversions to and from float. While that wastes a few nanoseconds, these functions aren't all that time-critical. But it seems worth fixing to remove possible reader confusion. Also, in the case of date2isoyear(), "result" is a very poorly chosen variable name because it is *not* the function's result. Rename it to "week", and do the same in date2isoweek() for consistency. Since this is mostly cosmetic, there seems little need for back-patch.
