Convert variable (integer) to percentage in asp.net mvc

Hello Community,

I'm trying to convert the variable integer data into percentage in creating a bar chart. However it seems it is not working. What I missed

string x1 = var_Product_name;                         
                  int y1 = Tools.ConvertToInt_02(var_Amount);     
                  int y2 = Tools.ConvertToInt_02(var_Amount)/ 100.ToString("0.00%");        //This is the code I used to convert the var_Amount to get the percentage and display as data series in bar graph together with the var_Amount value however this isn't working

BarChartData_Product_Records_Data_View.Add(new BarChartSourceData_Product_Records_Data_View(x1, y1, y2));

Mathematically, a percentage is usually less than 1. In C# an integer is a number between -32,768 and 32,767 and therefore cannot be a percentage. In C# a decimal type or float can represent a number that is less than 1.

If your integer value is actually an implied decimal (x 100) then you need to divide by 100 and cast to a decimal.

class Program { static void Main(string[] args) { int val = 45; Console.WriteLine( ((decimal)val / 100).ToString("0.00%")); } }

Results

45.00%

Hi @ika palad ,
You could use double or decimal.

int y2= Convert.ToInt32(Math.Round(((double)var_Amount) * 100, 0));
