@1@ Serializes the internal state of the pseudo-random number engine as a sequence of decimal numbers separated by one or more spaces, and inserts it to the stream. The fill character and the formatting flags of the stream are ignored and unaffected.

@2@ Restores the internal state of the pseudo-random number engine from the serialized representation, which was created by an earlier call to  using a stream with the same imbued locale and the same  and. If the input cannot be deserialized, is left unchanged and  is raised on.

If a textual representation is written using and that representation is restored into the same or a different object  of the same type using, then.

The textual representation is written with set to | and the fill character set to the space character. The textual representation of the engine's internal state is a set of decimal numbers separated by spaces.

Return value
