Set 0 at Decimal place if no value found

Question

I need to set “0” at the end of the decimal place dynamically if less integer number found after decimal place.

Suppose we have value: “535.8” Now I need to set it as “535.800” I have following code:

string cost = "535.8";
string decplace = "3";

decimal price = decimal.Round(Convert.ToDecimal(cost), Convert.ToInt32(decplace));
Console.WriteLine(price);
Console.ReadLine();

Unable to get 535.800.

How can I achieve this?

Answer 1

You can convert price to string and show upto 3 decimal places with 0's at end.

            string cost = "535.8";
            string decplace = "3";

            decimal price = decimal.Round(Convert.ToDecimal(cost), Convert.ToInt32(decplace));
            //string.Format("{0:N2}", price);
            Console.WriteLine(string.Format("{0:N3}", price));

Answer 2

price.ToString("N3")

Standard Numeric Format Strings: The Numeric ("N") Format Specifier

So if the number of decimal should be dynamic:

int numDecimalPlaces = 3;
Console.WriteLine(price.ToString("N" + numDecimalPlaces));

Answer 3

You can use string.Format() to make it possible:

Console.WriteLine(string.Format("{0:N3}", d));

So in your code:

string cost = "535.8";
string decplace = "3";

decimal price = decimal.Round(Convert.ToDecimal(cost), Convert.ToInt32(decplace));
Console.WriteLine(string.Format("{0:N" + decplace + "}", price);
Console.ReadLine();
