void discard( unsigned long long z );
(since C++11)

Advances the internal state by z times. Equivalent to calling operator() z times and discarding the result

Contents

[edit] Parameters

z - integer value specifying the number of times to advance the state by

[edit] Return value

(none)

[edit] Complexity

[edit] Notes

For some engines, "fast jump" algorithms are known, which advance the state by many steps (order of millions) without calculating intermediate state transitions, although not necessarily in constant time.
