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.

### Parameters

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

### Return value

(none)

### Complexity

No worse than the complexity of z consecutive calls to operator().

### 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.
