Remove 0s from the end of a decimal value [duplicate]

Answer 1

string.Format("{0:0.#####}", 0.0030)

or

var money=1.3000m;
money.ToString("0.#####");

For future reference I recommend the .NET Format String Quick Reference by John Sheehan.

Answer 2

Hmm, this is a display formatting issue (the zeros are added when you convert the decimal to a string).

You need to see where in code you are seeing the trailing zeros. Is it after a call to .ToString()? Try playing around with the different formatting strings:

.ToString("#");
.ToString("0.00");
.ToString("#.##");

And so on. The best way to do this is just to experiment with the different possible values.

Answer 3

I use the following. It ensures that any decimal (for which the max precision is 29 decimal places) will show all available digits of precision without trailing zeros, and without your code needing to have a long ugly string of hash marks.

if (value is Decimal)
   value = ((Decimal)value).ToString("0.".PadRight(29, '#'), culture);

Answer 4

 public static string GentlyRemoveEndZeros(string input)
        {
          //  if (input == null) return null;
          //  if (input == "") return "";
            if (input.Contains(".")) return input.TrimEnd('0').TrimEnd('.');
            return input;
        }

Answer 5

You can also modify the decimal itself so that any ToString() will give you what you want (more details in my answer here) :

public static decimal Normalize(decimal value)
{
    return value/1.000000000000000000000000000000000m;
}

Answer 6

decimal value = 0.0030m;
value.ToString(“G29″);

Edit: The G formatter does work, the only problem is that it jumps to scientific notation if there are too many significant figures in the original decimal. Not so ideal.

See the "The General ("G") Format Specifier" documentation here: http://msdn.microsoft.com/en-us/library/dwhawy9k.aspx#GFormatString

I'm on lunch, so I did a little test:

decimal d1 = 0.000100m;
decimal d2 = 0.001000000000000000000000m;
decimal d3 = 0.000000000000001000000000m;

Console.WriteLine(Environment.NewLine + "input decimal: 0.000100m");
Console.WriteLine("G         " + d1.ToString("G"));
Console.WriteLine("G29       " + d1.ToString("G29"));
Console.WriteLine("0.####### " + d1.ToString("0.#######"));

Console.WriteLine(Environment.NewLine + "input decimal: 0.001000000000000000000000m");
Console.WriteLine("G         " + d2.ToString("G"));
Console.WriteLine("G29       " + d2.ToString("G29"));
Console.WriteLine("0.####### " + d2.ToString("0.#######"));

Console.WriteLine(Environment.NewLine + "input decimal: 0.000000000000001000000000m");
Console.WriteLine("G         " + d3.ToString("G"));
Console.WriteLine("G29       " + d3.ToString("G29"));
Console.WriteLine("0.####### " + d3.ToString("0.#######"));

Output:

input decimal: 0.000100m
G         0.000100
G29       0.0001
0.####### 0.0001

input decimal: 0.001000000000000000000000m
G         0.001000000000000000000000
G29       0.001
0.####### 0.001

input decimal: 0.000000000000001000000000m
G         0.000000000000001000000000
G29       1E-15
0.####### 0
