问题描述

Double total = Convert.ToDouble(dt.Rows[0]["Amount_with_markup"]);
                   Double paid = Convert.ToDouble(txtpaid.Text);
                   Double rem =Math.Round(total - paid);
                   txtremaining.Text = rem.ToString(".####");

推荐答案

您好，



。## ## 最大小数点后4位。请尝试 .0000 ：

Hi,

.#### is max. 4 decimal places. Try .0000 instead:

txtremaining.Text = rem.ToString(".0000");

希望这有帮助。

Hope this helps.

你也可以处理你的Math.Round只显示4个小数位。

You can also handle only showing 4 decimal places in your Math.Round.

Double total = Convert.ToDouble(20.04353450);
Double paid = Convert.ToDouble(19.25641654);
Double rem = Math.Round(total - paid, 4, MidpointRounding.AwayFromZero);
txtremaining.Text = rem.ToString();
