public static member function
<random>
static constexpr result_type min();
Minimum value
Returns the minimum value potentially returned by member operator().
If member constant increment (an alias of template parameter c) is zero, the minimum is 1u, otherwise, it is zero.
Return value
0u, if increment is zero.
1u, otherwise.
result_type is a member type, defined as an alias of the first class template parameter (UIntType).
