I want to display a number in a report, however I only want to show any decimal points if they are present and the I only want to show 1 decimal space.
e.g. if the number is 12 then I want to show 12
If the number is 12.1 then I want to show 12.1
If the number is 12.11 then I want to show 12.1
I had a very similar problem a while ago and the answer is to use a format string when converting the number to a string. The way to solve your issue is to use a custom numeric format string of "0.#"
double x = 12; double y = 12.1; double z = 12.11; Console.WriteLine(x.ToString("0.#")); Console.WriteLine(y.ToString("0.#")); Console.WriteLine(z.ToString("0.#"));
Will give you the following output:
