1) Serializes the internal state of the pseudo-random number engine
e as a sequence of decimal numbers separated by one or more spaces, and inserts it to the stream ost. 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
e from the serialized representation, which was created by an earlier call to operator<< using a stream with the same imbued locale and the same CharT and Traits. If the input cannot be deserialized, e is left unchanged and failbit is raised on ist
If a textual representation is written using os << x and that representation is restored into the same or a different object y of the same type using is >> y, then x==y.
The textual representation is written with os.''fmtflags'' set to ios_base::dec|ios_base::left 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.
