public static member function
<random>
static constexpr result_type max();
Maximum value
Returns the maximum value potentially returned by member operator(), which for linear_congruential_engine is modulus-1 (where modulus is a member constant, alias of the fourth template parameter, m).
Return value
modulus-1
result_type is a member type, defined as an alias of the first class template parameter (UIntType).
