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

I have end up with this variant:

public static string Decimal2StringCompact(decimal value, int maxDigits)
    {
        if (maxDigits < 0) maxDigits = 0;
        else if (maxDigits > 28) maxDigits = 28;
        return Math.Round(value, maxDigits, MidpointRounding.ToEven).ToString("0.############################", CultureInfo.InvariantCulture);
    }

Advantages:

you can specify the max number of significant digits after the point to display at runtime;

you can explicitly specify a round method;

you can explicitly control a culture.
