retrieve a copy of the formatted value, use a specification that lets
@code{read} reconstruct the value. To format numbers in this
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}
can mishandle negative integers. @xref{Input Functions}.
integers you can also use @samp{%d}, @samp{#x%x} and @samp{#o%o}.
Other formats do not guarantee preservation of all values; for example,
@samp{%g} can lose precision and type and does not preserve NaN or
infinity. @xref{Input Functions}.
The functions described in this section accept a fixed set of
specification characters. The next section describes a function
