C# rounding MidpointRounding.AwayFromZero

四舍五入 在计算中 经常使用到,但是如果使用 Math.Round,just rounding up
在Math.Round内传入MidpointRounding.AwayFromZero枚举,The rounding effect can be achieved,

            Debug.Log($"四舍五入{
      66.6}...{
      (int)Math.Round(66.6, MidpointRounding.AwayFromZero)}");
            Debug.Log($"四舍五入{
      66.5}...{
      (int)Math.Round(66.5, MidpointRounding.AwayFromZero)}");
            Debug.Log($"四舍五入{
      66.4}...{
      (int)Math.Round(66.4, MidpointRounding.AwayFromZero)}");

            Debug.Log($"四舍五入{
      66.6}...{
      (int)Math.Round(66.6)}");
            Debug.Log($"四舍五入{
      66.5}...{
      (int)Math.Round(66.5)}");
            Debug.Log($"四舍五入{
      66.4}...{
      (int)Math.Round(66.4)}");
