std::numeric_limits<T>::is_modulo

The value of std::numeric_limits<T>::is_modulo is true for all arithmetic types T that handle overflows with modulo arithmetic, that is, if the result of addition, subtraction, multiplication, or division of this type would fall outside the range [min(), max()], the value returned by such operation differs from the expected value by a multiple of max() - min() + 1.
is_modulo is false for signed integer types, unless the implementation defines signed integer overflow to wrap.
