std::float_round_style(3) C++ Standard Libary std::float_round_style(3) NAME std::float_round_style - std::float_round_style Synopsis Defined in header <limits> enum float_round_style { round_indeterminate = -1, round_toward_zero = 0, round_to_nearest = 1, round_toward_infinity = 2, round_toward_neg_infinity = 3 }; Enumeration constants of type std::float_round_style indicate the rounding style used by floating-point arithmetics whenever a result of an expres- sion is stored in an object of a floating-point type. The values are: Enumeration constants Name Definition std::round_indeterminate Rounding style cannot be determined std::round_toward_zero Rounding toward zero std::round_to_nearest Rounding toward nearest representable value std::round_toward_infinity Rounding toward positive infinity std::round_toward_neg_infinity Rounding toward negative infinity See also round_style identifies the rounding style used by the type [static] (public static member constant) FE_DOWNWARD FE_TONEAREST floating-point rounding direction FE_TOWARDZERO (macro constant) FE_UPWARD (C++11) http://cppreference.com 2022.07.31 std::float_round_style(3)
