Round toward −∞:朝向-∞舍入而在Java 中,默认舍入模式为 RoundingMode.HALF_EVEN,即 "Round to nearest, ties to even" 该舍入模式也被称为 "Banker's rounding",在统计学上这种模式可以使累计的误差最小4.手动计算IEEE754值示例以常见的 0.1 和 float 为例: 0.1(10)=0.0001100110011...(2)=(−...

For each finite floating-point value and a given floating-point type, there is a contiguous region of the real number line which maps to that value. Under the default round to nearest rounding policy (JLS 15.4), this contiguous region for a value is typically one ulp (unit in the last ...

Let R be the set of all decimals that round to m according to the usual round to nearest rounding policy of IEEE 754 floating-point arithmetic. Let p be the minimal length over all decimals in R. When p≥ 2, let T be the set of all decimals in R with length p. Otherwise, ...
