public static member function
<random>
static constexpr result_type max();
Maximum value
Returns the maximum value potentially returned by member operator(), which for independent_bits_engine is 2w-1, where w is the second class template parameter (the number of significant bits per generated number).
Return value
2w-1
result_type is a member type, defined as an alias of the type of the numbers generated by the base engine.
