Non-member functions

operator==operator!=

operator<<operator>>

static constexpr result_type max();		(since C++11)

Returns the maximum value potentially generated by the random-number engine. This value is equal to 2w
- 1, where w is the template parameter also accessible as static member word_size.

Parameters

(none)

Return value

The maximum potentially generated value.

Complexity

Constant
