Since I am using this to remove trailing zeros when there is no value behind decimal:
decimal.Parse(variable).ToString("G29")
But it doesn't give thousand separator. For example:
string amount = "54321.00"
string amount2 = "54321.55"
string parsed = decimal.Parse(amount).ToString("G29");
string parsed2 = decimal.Parse(amount2).ToString("G29");
//parsed = 54321
//parsed2 = 54321.55
//my goal
//parsed = 54,321
//parsed2 = 54,321.55
Is there any better format type?
Use a custom format
string format = "#,#.##";
decimal noDecimalPlaces = 54321.00m;
decimal decimalPlaces = 54321.55m;
Console.WriteLine(noDecimalPlaces.ToString(format)); // writes 54,321
Console.WriteLine(decimalPlaces.ToString(format)); // writes 54,321.55
You can read more about formatting decimals on msdn.
The way this works
The latter part .## specifies that you allow up to two decimal places. The former part #,# specifies that you want to separate the integer part of your value.
Note:
The number formatting is still culture specific, so for cultures that use , as the decimal separator and . for digit grouping your numbers will be displayed as 54.321 and 54.321,55 instead. You can find out more about formatting in .NET here.

I am trying to convert a position from a string to double , to use it on map.
The string position is in the format like:
latString: "31,92002306867021"
Using:
double lat = Convert.ToDouble(latString, CultureInfo.InvariantCulture);
the result is wrong : 3,19200230686702E+15
Using Convert.ToDouble(latString) give me number without "."
What is the right way to manage that type of convertion?
The invariant culture is associated with the English culture and thus uses . as a decimal separator. The , will be interpreted as a thousands separator.
If you pass in a culture that uses commas (e.g. nl-NL), it will work:
double lat = Convert.ToDouble("31,1234", CultureInfo.CreateSpecificCulture("nl-NL"));
If you are absolutely certain the input strings can only contain valid latitudes/longitudes (i.e. numbers will never exceed 1,000), then you could also use string replacement:
double lat = Convert.ToDouble("31,1234".Replace(',', '.'), CultureInfo.InvariantCulture);
It seems that you have latString in some different culture that uses , as a thousand separator which is just ignored while converting to floating point:
"31,92002306867021" -> 3192002306867021 -> 3.19200230686702E+15
First, check your current culture, it may well appear that it uses , as a decimal separator:
string latString = "31,92002306867021";
// Current culture
double result = Convert.ToDouble(latString);
If not, you can try to replace , with a current decimal separator:
string latString = "31,92002306867021";
// be careful and culture specific: naive
// latString.Replace(",", ".")
// will cause problems with some cultures
// (e.g. ru-Ru which uses "." as a thousand separator)
string value = latString.Replace(",",
CultureInfo.CurrentCulture.NumberFormat.NumberDecimalSeparator);
double result = Convert.ToDouble(value);
I need to display a number with commas and a decimal point.
Eg:
Case 1 : Decimal number is 432324 (This does not have commas or decimal points).
Need to display it as: 432,324.00.
Not: 432,324
Case 2 : Decimal number is 2222222.22 (This does not have commas).
Need to display it as: 2,222,222.22
I tried ToString("#,##0.##"), but it is not formatting it correctly.
int number = 1234567890;
number.ToString("#,##0.00");
You will get the result 1,234,567,890.00.
Maybe you simply want the standard format string "N", as in
number.ToString("N")
It will use thousand separators, and a fixed number of fractional decimals. The symbol for thousands separators and the symbol for the decimal point depend on the format provider (typically CultureInfo) you use, as does the number of decimals (which will normally by 2, as you require).
If the format provider specifies a different number of decimals, and if you don't want to change the format provider, you can give the number of decimals after the N, as in .ToString("N2").
Edit: The sizes of the groups between the commas are governed by the
CultureInfo.CurrentCulture.NumberFormat.NumberGroupSizes
array, given that you don't specify a special format provider.
Try with
ToString("#,##0.00")
From MSDN
*The "0" custom format specifier serves as a zero-placeholder symbol. If the value that is being formatted has a digit in the position where the zero appears in the format string, that digit is copied to the result string; otherwise, a zero appears in the result string. The position of the leftmost zero before the decimal point and the rightmost zero after the decimal point determines the range of digits that are always present in the result string.
The "00" specifier causes the value to be rounded to the nearest digit preceding the decimal, where rounding away from zero is always used. For example, formatting 34.5 with "00" would result in the value 35.*
I had the same problem. I wanted to format numbers like the "General" format in spreadsheets, meaning show decimals if they're significant, but chop them off if not. In other words:
1234.56 => 1,234.56
1234 => 1,234
It needs to support a maximum number of places after the decimal, but don't put trailing zeros or dots if not required, and of course, it needs to be culture friendly. I never really figured out a clean way to do it using String.Format alone, but a combination of String.Format and Regex.Replace with some culture help from NumberFormatInfo.CurrentInfo did the job (LinqPad C# Program).
string FormatNumber<T>(T number, int maxDecimals = 4) {
return Regex.Replace(String.Format("{0:n" + maxDecimals + "}", number),
#"[" + System.Globalization.NumberFormatInfo.CurrentInfo.NumberDecimalSeparator + "]?0+$", "");
}
void Main(){
foreach (var test in new[] { 123, 1234, 1234.56, 123456.789, 1234.56789123 } )
Console.WriteLine(test + " = " + FormatNumber(test));
}
Produces:
123 = 123
1234 = 1,234
1234.56 = 1,234.56
123456.789 = 123,456.789
1234.56789123 = 1,234.5679
Try with
ToString("#,##0.###")
Produces:
1234.55678 => 1,234.556
1234 => 1,234
For Razor View:
$#string.Format("{0:#,0.00}",item.TotalAmount)
CultureInfo us = new CultureInfo("en-US");
TotalAmount.ToString("N", us)
Your question is not very clear but this should achieve what you are trying to do:
decimal numericValue = 3494309432324.00m;
string formatted = numericValue.ToString("#,##0.00");
Then formatted will contain: 3,494,309,432,324.00
All that is needed is "#,0.00", c# does the rest.
Num.ToString("#,0.00"")
The "#,0" formats the thousand separators
"0.00" forces two decimal points
If you are using string variables you can format the string directly using a : then specify the format (e.g. N0, P2, etc).
decimal Number = 2000.55512016465m;
$"{Number:N}" #Outputs 2,000.55512016465
You can also specify the number of decimal places to show by adding a number to the end like
$"{Number:N1}" #Outputs 2,000.5
$"{Number:N2}" #Outputs 2,000.55
$"{Number:N3}" #Outputs 2,000.555
$"{Number:N4}" #Outputs 2,000.5551
string Mynewcurrency = DisplayIndianCurrency("7743450.00");
private string DisplayIndianCurrency(string EXruppesformate)
{
string fare = EXruppesformate;
decimal parsed = decimal.Parse(fare, CultureInfo.InvariantCulture);
CultureInfo hindi = new CultureInfo("en-IN");
// string text = string.Format(hindi, "{0:c}", parsed);if you want <b>Rs 77,43,450.00</b>
string text = string.Format(hindi, "{0:N}", parsed); //if you want <b>77,43,450.00</b>
return ruppesformate = text;
}
For anyone looking at this now, and getting the "No overload for method 'ToString' takes 1 argument" when using:
TotalNumber.ToString("N")
My solution has been to use :
TotalNumber.Value.ToString("N")
I often get stuck on this when working directly inside an MVC View, the following wasn't working:
#Model.Sum(x => x.Number).ToString("N")
Whereas this works:
#Model.Sum(x => x.Number).Value.ToString("N")
Suppose I have a list of decimal numbers that I must format with a comma every three places, plus the appropriate number of digits after the decimal point. I want to use the .net string.Format method.
I want it to work like this:
string format = ???;
string s1 = string.Format(format, "1500"); // "1,500"
string s2 = string.Format(format, "1500.25"); // "1,500.25"
string s3 = string.Format(format. "3.1415926358979"); // "3.1415926358979"
I have seen other answers where the digits after the decimal are either limited to a fixed number of digits or truncated entirely, but this doesn't work for my application. I want to add the comma-separator to the whole part of the number, but keep the digits after the decimal exactly as they are.
First problem, you need to parse your strings before you can format them. There maybe some lose of precision. Then you need to decide what your maximum amount of precision you need is. Then you can do something like this:
string format = "{0:#,##0.#############}";
string s1 = string.Format(format, double.Parse("1500")); // "1,500"
string s2 = string.Format(format, double.Parse("1500.25")); // "1,500.25"
string s3 = string.Format(format, double.Parse("3.1415926358979")); // "3.1415926358979"
The # after the decimal place is a place holder for a decimal digit. If there are no more digits it won't show trailing zeros.
If being limited to a number of decimal places or possibly losing precision when converting to double. You could do something really cludgy like this:
public static string DecimalFormatCludge(string original)
{
var split = original.Split('.');
return string.Join(".", (new [] { int.Parse(split[0]).ToString("#,##0")}).Concat(split.Skip(1)));
}
This will split on the . in the string, parse the first part as an int, convert it back to a string correctly formatted and then just stick the decimal part back on (if there is one)
something like this?
string s1 = format.ToString("#,##0.00");
The format is something like this:
string format = "{0:#,##.##################}";
In mvc I have formatted a numeric value using a comma as the number group separator as is specified in the Indian numbering system:
PaymentReceived = String.Format(new CultureInfo("en-IN", true), "{0:n}", t.PaymentReceived)
Later, I need to parse the string back to a numeric value. Here the FieldValue is of type long, while the right side value is of type string. How do I get the conversion to long?
I already have tried to do he following, but this is throwing an error message (the input string was not in correct format):
FieldValue = Convert.ToInt64( String.Format(new CultureInfo("en-IN", true), "{0:n}", t1.FieldValue))
As pointed out in the comment, you do not need to format a string with commas to convert it to a long. The commas are purely a presentation issue and None of the primitive number data types(int, long, double...) will maintain them.
To convert the string to long, do this.
FieldValue = Convert.ToInt64(t1.FieldValue)
To display the value as a comma separated number, do this
string formattedString = FieldValue.ToString("N0")
Your problem is not with the number group separator in your string. Your problem is that, when you formatted your number, you used the "{0:n}" format but did not specify a precision. From the docs:
If the precision specifier is omitted, the number of decimal places is defined by the current NumberFormatInfo.NumberDecimalDigits property.
For "en-IN" the default number of digits is 2. Thus your number, despite being a long, is being formatted with decimal digits. I.e. if you do:
long val = 1111111011;
var s = String.Format(new CultureInfo("en-IN", true), "{0:n0}", val);
Console.WriteLine(s);
The result looks like 1,11,11,11,011.00.
Later, you try to parse the string back to a long -- which throws a FormatException. The string is in an invalid format for a long because it contains a decimal point while long can only have integer values.
To avoid this problem, you could:
Format the initial value without a decimal point by using a precision of zero:
String.Format(new CultureInfo("en-IN", true), "{0:n0}", t.PaymentReceived)
Parse to decimal and round:
(long)Math.Round(decimal.Parse(s, new CultureInfo("en-IN", t.PaymentReceived)));
I have this custom extension that should format a decimal number with a custom amount of digits after comma.
public static decimal FormatDecimal(this decimal value, int decimalSeparator = 2)
{
decimal returnValue = Math.Round(value, decimalSeparator, MidpointRounding.AwayFromZero);
return returnValue;
}
The problem is that doesn't work as expected.
If I do like this:
decimal number = 12345;
and then:
decimal formatedNumber = number.FormatDecimal(2);
the result should be:
12345.00
instead the result is:
12345
What I am doing wrong?
Here's the extension function working
public static string FormatDecimal(this decimal value, int decimalSeparator = 2)
{
return value.ToString(string.Format("0.{0}", new string('0', decimalSeparator)));
}
I think the right way is to using The "0" custom format specifier;
Replaces the zero with the corresponding digit if one is present;
otherwise, zero appears in the result string.
For example;
decimal d = 12345;
Console.WriteLine(d.ToString("#.00")); // 12345.00
You're probably looking to format the string representation of your decimal instead. Try this:
decimal myNumber = 12345.67m;
string formattedNumber = myNumber.ToString("N3");
Console.WriteLine(formattedNumber); // Prints "12345.670"

From MSDN:
Standard numeric format strings are used to format common numeric types. A standard numeric format string takes the form Axx, where:
A is a single alphabetic character called the format specifier. Any numeric format string that contains more than one alphabetic character, including white space, is interpreted as a custom numeric format string. For more information, see Custom Numeric Format Strings.
xx is an optional integer called the precision specifier. The precision specifier ranges from 0 to 99 and affects the number of digits in the result. Note that the precision specifier controls the number of digits in the string representation of a number. It does not round the number itself. To perform a rounding operation, use the Math.Ceiling, Math.Floor, or Math.Round method.
When precision specifier controls the number of fractional digits in the result string, the result strings reflect numbers that are rounded away from zero (that is, using MidpointRounding.AwayFromZero).
You should specify the formatting when you display the string.
What you need is to do the following, when you convert to string:
String.Format("{0:0.00}", formatedNumber);
