std::is_integral_v vs std::numeric_limits::is_integer

`std::is_integral_v` returns `0` while `std::numeric_limits::is_integer` returns `1`.
(`using myuint256 = boost::multiprecision::number boost::multiprecision::checked, boost::multiprecision::unchecked), void>>;`)

It is usually assumed that both calls are equivalent.
Is this desired behavior or can it be considered a bug or missing feature?

The issue provides no repository files, tests, or entry points. Reproduce the supplied type and compare the two trait results, then inspect the relevant Multiprecision trait and numeric-limits behavior; done requires determining whether the difference is intentional or defining a concrete correction.
