Best way to display decimal without trailing zeroes

Question

Is there a display formatter that will output decimals as these string representations in c# without doing any rounding?

// decimal -> string

20 -> 20         


        

Answer 1

Do you have a maximum number of decimal places you'll ever need to display? (Your examples have a max of 5).

If so, I would think that formatting with "0.#####" would do what you want.

    static void Main(string[] args)
    {
        var dList = new decimal[] { 20, 20.00m, 20.5m, 20.5000m, 20.125m, 20.12500m, 0.000m };

        foreach (var d in dList)
            Console.WriteLine(d.ToString("0.#####"));
    }

Answer 2

You can create extension method

public static class ExtensionMethod {
  public static decimal simplify_decimal(this decimal value) => decimal.Parse($"{this:0.############}");
}
