+objects.  If newval is True, future calls to stat() return floats, if
+it is False, future calls return ints.  If newval is omitted, return
+the current setting.
+
+For compatibility with older Python versions, accessing
+\class{stat_result} as a tuple always returns integers. For
+compatibility with Python 2.2, accessing the time stamps by field name
+also returns integers. Applications that want to determine the
+fractions of a second in a time stamp can use this function to have
+time stamps represented as floats. Whether they will actually observe
+non-zero fractions depends on the system.
+
+Future Python releases will change the default of this settings;
+applications that cannot deal with floating point time stamps can then
+use this function to turn the feature off.
+
+It is recommended that this setting is only changed at program startup
+time in the \var{__main__} module; libraries should never change this
+setting. If an application uses a library that works incorrectly if
+floating point time stamps are processed, this application should turn
+the feature off until the library has been corrected.

+\item The \function{stat} family of functions can now report fractions
+of a second in a time stamp. Similar to \function{time.time}, such
+time stamps are represented as floats.
+
+During testing, it was found that some applications break if time
+stamps are floats. For compatibility, when using the tuple interface
+of the \class{stat_result}, time stamps are represented as integers.
+When using named fields (first introduced in Python 2.2), time stamps
+are still represented as ints, unless \function{os.stat_float_times}
+is invoked:
+
+\begin{verbatim}
+>>> os.stat_float_times(True)
+>>> os.stat("/tmp").st_mtime
+1034791200.6335014
+\end{verbatim}
+
+In Python 2.4, the default will change to return floats.
+
+Application developers should use this feature only if all their
+libraries work properly when confronted with floating point time
+stamps (or use the tuple API). If used, the feature should be
+activated on application level, instead of trying to activate it on a
+per-use basis.
