问题描述

如何四舍五入十进制数字..?
假设我有一个像25.75这样的数字，我必须将其四舍五入为26.00.所以如何通过我不理解的代码来解决这个问题.所以请帮帮我..它很紧急.我必须在Windows应用程序中解决. "h2_lin">解决方案

 十进制 d =  25 . 75 ;
d = Math.Round(d); // 因此，d = 26 
字符串 a = d.ToString(" ); // 以0.00格式在文本框中显示它 

祝您编码愉快！

好吧，您可以在数学库中使用Round:
http://msdn.microsoft.com/zh-我们/library/system.math.round%28v=vs.110%29.aspx [ http://msdn.microsoft.com/en-us/library/7d101hyf.aspx [ ^ ]

还是地板或天花板，取决于您的要求:
http://msdn.microsoft.com/en-us/library/system.math％28v = vs.71％29.aspx [ http://msdn.microsoft.com/en-us/library/dwhawy9k.aspx [ ^ ]

试试这个

 Console.WriteLine(" ，Math.Ceiling( 25 . 75 )));
Console.WriteLine(" ，Math.Ceiling( 25 . 45 ))；
Console.WriteLine(" ，Math.Floor( 25 . 75 ))；
Console.WriteLine(" ，Math.Floor( 25 . 45 ))；
Console.WriteLine(" ，Math.Round( 25 . 75 ))；
Console.WriteLine(" ，Math.Round( 25 . 45 ))); 

How to Round off A decimal number..?
suppose I have a number like 25.75,and I have to round it into 26.00.so how to solve this through code i donot understand.so please help me out..its urgent.I have to solve in windows application.

解决方案

decimal d= 25.75;
d = Math.Round(d);// so, d=26
string a = d.ToString("0.00");//to show it in textbox in 0.00 format

Happy Coding!

Well, you can use Round in the Math library:
http://msdn.microsoft.com/en-us/library/system.math.round%28v=vs.110%29.aspx[^]
or Truncate:
http://msdn.microsoft.com/en-us/library/7d101hyf.aspx[^]

Or floor or ceileing, depending on your requirements:
http://msdn.microsoft.com/en-us/library/system.math%28v=vs.71%29.aspx[^]

and to show the number in any format:
http://msdn.microsoft.com/en-us/library/dwhawy9k.aspx[^]

Try this

Console.WriteLine("Math.Ceiling(25.75) = {0}", Math.Ceiling(25.75));
Console.WriteLine("Math.Ceiling(25.45) = {0}", Math.Ceiling(25.45));
Console.WriteLine("Math.Floor(25.75) = {0}", Math.Floor(25.75));
Console.WriteLine("Math.Floor(25.45) = {0}", Math.Floor(25.45));
Console.WriteLine("Math.Round(25.75) = {0}", Math.Round(25.75));
Console.WriteLine("Math.Round(25.45) = {0}", Math.Round(25.45));
