 retrieve a copy of the formatted value, use a specification that lets

 reversible way you can use @samp{%s} and @samp{%S}, to format just
-integers you can also use @samp{%d}, and to format just nonnegative
-integers you can also use @samp{#x%x} and @samp{#o%o}.  Other formats
-may be problematic; for example, @samp{%d} and @samp{%g} can mishandle
-NaNs and can lose precision and type, and @samp{#x%x} and @samp{#o%o}
