Visual Studio 2015 net 4.6.1 四捨六入五成雙 錯誤

最近再試，發現 Math.round() 又正確了....奇了！ 116.55出來是116

==========
一般的說法是Math.round()

但實際上跑

decimal num = 116.55
Math.round(num)

結果是 117  這是錯的！！


所以

參考這個

改成

decimal GetFrag1(decimal input,int digit) //這個四捨六入五成雙才正確
{
            if (digit < 0) { return Math.Floor(input); }
            double pow = Math.Pow(10, digit);
            decimal sign = input >= 0 ? 1 : -1;
            return sign * Math.Floor(sign * input * (decimal)pow) / (decimal)pow;
}


GetFrag1(num, 0).ToString()

結果 116
