How to convert this string to decimal 0.55 exactly.
Decimal.parse("0,55")
I need to get exact value excluding leading zeroes.
This should fix your problem (if I understand the problem, that is):
var number = decimal.Parse("0,55".Replace(',', '.'), CultureInfo.InvariantCulture);
EDIT
Not every culture uses the point (.) symbol as the decimal separator. If you don't specify a format provider, the framework defaults to the current culture. I'm guessing that in this particular case, the decimal.Parse() method was interpreting "0,55" as decimal 55.0.

Is it possible to have such string format for XAML element's Binding that would display a 'negated' decimal in XAML element?
Like '12.04' should be displayed as '-12.04' and '-4.57' as '4.57'. Multiplying by -1, or using Converter won't work for my task - I need exactly a string format
In StringFormat for a decimal number binding, you can supply formatting for the positive, and the negative value. The first one, separated with a semicolon, is the positive, the second one the negative. If, instead of putting the negative sign on the right side, you put it on the left side, it is only going to be used for positive numbers.
{Binding SomeValue, StringFormat=-0.##;0.##}

For a given decimal with precision of 8 like 0.00010000, I would like to get the decimal places without the trailing zeros.
All methods that I tested returned 8, and in this case should be 4.
You can use string value=decimalValue.ToString("0.########") this will convert the value into a string and show up to 8 decimal places, without trailing zeros. Eg. 1.05000000 - > 1.05, 1.00000001->1.00000001. Then value.Split('.').ToList().ElementAt(1).Length
string output = Regex.Replace("0.00010000", #"[0]*$", "");
decimal someDecimal = 0.00010000000m;
Console.WriteLine(someDecimal.ToString().TrimEnd('0'));

I am attempting to write out to a fixed format text file and am having some trouble formatting the numbers properly. It needs to be padded with leading zeros and an implied decimal.
Example:
43.80
The output would need to be:
0000004380
So far, I have attempted to convert the double to a string, replace the decimal, and then pad with "0".
((amount.ToString()).Replace(".","")).PadLeft(10, '0')
The problem with this is when the number ends with zeros. The above example comes out as:
0000000438
Any suggestions?
decimal value = 34.80M;
int intVal = (int)(value * 100);
return intVal.ToString("0000000000");
You could try:
((string.Format("{0:0.00}", amount)).Replace(".","")).PadLeft(10, '0')
That way you don't lose the 2nd decimal place when the value is 0.
You can pass a .ToString() format string in as described in this article:
https://msdn.microsoft.com/en-us/library/dwhawy9k(v=vs.110).aspx
Does the incoming value always have two decimal places? If so, you could multiply by 100 to get rid of the decimal, and then to .ToString("D10")
(Int)(43.80 * 100).ToString("D10")
This should do the job : $"{(int)(amount * 100):D010}"

i have standard windows textbox that is formatted for currency but there is minor issue, when the user enter a value like 19999.9999999, this get rounded to 20000.00. If the user enters the value as 19999.99 this value will not get rounded. In the big industry, what is the correct way to format this number?
I need this to be rounded without harming the property value!
How about Math.Round.
try like this
decimal dValue = Math.Round(19999.999999M, 3);
Take a look at the msdn for complete reference of Math.Round() method.

I want convert 1,2,3,4,5,6,7,8,9,10 String to Double.
I tried Convert.ToDouble(String); and Double.Parse(String); but returned 1.0
How to convert multi comma string to double?
Thanks for help.
From the looks of your question you actually have 10 numbers not 1. Use this code:
var nums = "1,2,3,4,5,6,7,8,9,10";
var digits = nums.Split(',').Select(r => Convert.ToDouble(r)).ToArray();
// the result will be an array of doubles, also this only works with .NET 3.5 or better.
Let me know if this works for you.
