Math.Rounddoes just that - round.
Math.Round就是这样 - 圆。
To format the number you may use .ToString(formatString)like so:
要格式化您可以使用的数字，.ToString(formatString)如下所示：
item.OtherFields["price"].ToString("0.00")

Use string format function
使用字符串格式函数
1. string.Format("{0:n2}", 200000000.8776);
2. string.Format("{0:n3}", 200000000.8776);
3. string.Format("{0:n2}", 0.3);
/* OUTOUT
1. 200,000,000.88
2. 200,000,000.878
3. 0.30
*/
