Hi,

I am getting a number which is the output of a division process.

I may get,

34
5.03
6.2
123.42

SO After formatting the string I should get two digit decimals not mattering if both decimals are zero I need to display Zero(0) rather than trimming Zero(0)

So My Expected output is shown as follows

34.00
5.03
6.20
123.42

Can anyone help to get rid of this problem

Use the following function in System.Math

Math.Round(34,2)

The output of above will be 34.00

No, it doesn't. Whether you use Math.Round(double)[^] or Math.Round(decimal)[^], they return a double, or decimal respectively.
It is up to a string formatting method to determine how many trailing zeroes an application shows.

You have to pass 2 parameters ie Math.Round('Your double or decimal number','number of decimals required. eg: 1 or 2 or 3 and so on')

You should use string.Format like in the next example:

C#

string.Format("{0:#,0.00}", yourNumber);
