std::numeri...round_error(3) C++ Standard Libary std::numeri...round_error(3) NAME std::numeric_limits::round_error - std::numeric_limits::round_error Synopsis static T round_error() throw(); (until C++11) static constexpr T round_error() noexcept; (since C++11) Returns the largest possible rounding error in ULPs (units in the last place) as defined by ISO 10967, which can vary from 0.5 (rounding to the near- est digit) to 1.0 (rounding to zero or to infinity). It is only meaningful if std::numeric_limits<T>::is_integer == false.
