This is my code :

C#

protected void txtPresent_TextChanged(object sender, EventArgs e)
   {
       decimal conclass, pres, abs;
       decimal avg;
       conclass = Convert.ToDecimal(txtCondClass.Text.Trim());
       pres = Convert.ToDecimal(txtPresent.Text.Trim());
       abs = conclass - pres;
       txtAbs.Text = abs.ToString();
       avg = pres * 100 / conclass;
       txtAvg.Text = avg.ToString();
   }

======OUTPUT ======
Getting like this
Total = 45
Present = 29
Absent = 16
Average = 64.444444444444444444444444444

Solution 2

Dear Friend,

do

Math.Round([Value],2)

for e.g. in your case:-

avg = Math.Round((pres * 100 / conclass),2);

Solution 3

If you need to represent only two decimal places then use:

C#

txtAvg.Text = avg.ToString("0.00");
