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
