How to add Zero(0) prefix and suffix in a value.(it should be Numeric or Decimal)

Hi Developers,
How to add zero(0) if the TextBox decimal value Length more than 1
My Reqiurements is as below

if TextBox value is =.1 should be insert as 00.10
if TextBox value is =1.0 should be insert as 1.00
if TextBox value is =1 should be insert as 1.00
if TextBox value is =1.000 should be insert as 1.00
if TextBox value is =0.1 should be insert as 0.10

if TextBox value is =1234 = should be insert as 1234
if TextBox value is =1234.22 = should be insert as 1234.22
if TextBox value is =1234.2= should be insert as 1234.20
if TextBox value is =1234.222 = should be insert as 1234.20

if the value decimal length is 1 or more than 1 na automatically add zero.
if Decimal value less than 2 or more than 2 digits
if 1.2 will be 1.20
if 1.222 will be 1.20 also

if i am done this task means my project is over.
I am tried but i cant able to get exact output.so anyone know please help me to how am done this task

Use Math.Round
Math.Round(mydoublevalue, 2);

In your code
tbtotal2.Text = Math.Round(total2, 2).ToString();

you can also try
// just two decimal places
String.Format("{0:0.##}", 123.4567); // "123.46"
String.Format("{0:0.##}", 123.4); // "123.4"
String.Format("{0:0.##}", 123.0); // "123"

can also combine "0" with "#".

String.Format("{0:0.0#}", 123.4567) // "123.46"
String.Format("{0:0.0#}", 123.4) // "123.4"
String.Format("{0:0.0#}", 123.0) // "123.0"

There are many ways to achieve task, see below snippet


String.Format("{0:0.00}", 140.6767554);        // "140.67"
String.Format("{0:0.00}", 140.1);             // "140.10"
String.Format("{0:0.00}", 140);              // "140.00"

Double d = 140.6767554;
Double dc = Math.Round((Double)d, 2);       //  140.67

decimal d = 140.6767554M;
decimal dc = Math.Round(d, 2);             //  140.67

=========
// just two decimal places
String.Format("{0:0.##}", 123.4567);      // "123.46"
String.Format("{0:0.##}", 123.4);         // "123.4"
String.Format("{0:0.##}", 123.0);         // "123"

can also combine "0" with "#".
String.Format("{0:0.0#}", 123.4567)       // "123.46"
String.Format("{0:0.0#}", 123.4)          // "123.4"
String.Format("{0:0.0#}", 123.0)

hope it helps

Thanks for all your replies.

i am try below code as your suggestion but i did not get exact output.

String.Format("{0:0.00}", 123.4567); // "123.46"
String.Format("{0:0.00}", 123.4); // "123.40"
String.Format("{0:0.00}", 123.0); // "123.00"

am using like below

String.Format("{0:0.00}", txt1.Text.Trim()); // "123.46"
String.Format("{0:0.00}", txt1.Text.Trim()); // "123.40"
String.Format("{0:0.00}", txt1.Text.Trim()); // "123.00"

So please suggest me to get exact output.

Below code is working these condition , that is
if 1.0 is ==1.10
if .1 is ==0.10
if 111.2222 is == 111.20

MyCode:
string val = "1234.22";
if (val.Split('.')[1].Length > 2)
{
val = val.Split('.')[0] + '.' + val.Split('.')[1].Substring(0, 1);
}
decimal d = Convert.ToDecimal(val);
string result = d.ToString("0.00");
but i want to add one more condition instead in my code that is
If i give value = 123 it should be 123.00 that's all
if 123 is == 123.00
i cant able to done this. so help me to add that condition instead of my code.

             string a = num +".00";
         }
