Char.IsDigit() is a subset of Char.IsNumber().

Some of the characters that are 'numeric' but not digits include 0x00b2 and 0x00b3 which are superscripted 2 and 3 ('²' and '³') and the glyphs that are fractions such as '¼', '½', and '¾'.

Note that there are quite a few characters that IsDigit() returns true for that are not in the ASCII range of 0x30 to 0x39, such as these Thai digit characters: '๐' '๑' '๒' '๓' '๔' '๕' '๖' '๗' '๘' '๙'.

This snippet of code tells you which code points differ:

static private void test()
{
    for (int i = 0; i <= 0xffff; ++i)
    {
        char c = (char) i;

        if (Char.IsDigit( c) != Char.IsNumber( c)) {
            Console.WriteLine( "Char value {0:x} IsDigit() = {1}, IsNumber() = {2}", i, Char.IsDigit( c), Char.IsNumber( c));
        }
    }
}

so bottom line, how do I determine if a char exists is one of `0123456789`? – Shimmy Weitzhandler Oct 26 '11 at 20:26

@Shimmy try to parse it into an int – Amicable Oct 19 '12 at 11:41

@shimmy if ("0123456789".Contains(c)) – Gerard Feb 25 '13 at 13:56
@Amicable, no need to parse to into, using BradleyUffner's solution, a char is like an int. – Shimmy Weitzhandler Feb 26 '13 at 09:36

Don't you mean `Char.IsNumber()` instead of `Char.IsNumeric` in the first line? – osvein Oct 22 '13 at 18:21

I think it's more readable to use `Char.MinValue` and `Char.MaxValue` in your example code. – Sam Dec 12 '13 at 04:38

@BradleyUffner, new programmers might get stuck trying to use double quotes instead of single quotes for the character literals. Here's the code in case anyone wants it: `character >= '0' && character <= '9'`. – Sam Dec 12 '13 at 05:15
This algorithm skip many Unicode numeric codepoints because it uses evaluates the whole range of UTF-16 code units as if they are codepoints in BMP. For example, ['AEGEAN NUMBER ONE' (U+10107)](http://www.fileformat.info/info/unicode/char/10107/index.htm). Use [Char.IsNumber String, Int32](https://learn.microsoft.com/en-us/dotnet/api/system.char.isnumber?view=netframework-4.7.2#System_Char_IsNumber_System_String_System_Int32_) on codepoints instead. – Tom Blodget Nov 18 '18 at 18:38

@Gerard Use `c >= '0' && c <= '9'` instead. It is shorter and more efficient. – aloisdg Mar 21 '19 at 21:49
Wow, a similar distinction hold for Haskell's `Data.Char.isDigit` and `Data.Char.isNumber`. – Enlico Nov 22 '19 at 21:11

I found the answer:

Char.IsNumber() determines if a Char is of any numeric Unicode category. This contrasts with IsDigit, which determines if a Char is a radix-10 digit.

Valid numbers are members of the following categories in UnicodeCategory:

DecimalDigitNumber
Decimal digit character, that is, a character in the range 0 through 9. Signified by the Unicode designation "Nd" (number, decimal digit). The value is 8.

LetterNumber
Number represented by a letter, instead of a decimal digit, for example, the Roman numeral for five, which is "V". The indicator is signified by the Unicode designation "Nl" (number, letter). The value is 9.

OtherNumber
Number that is neither a decimal digit nor a letter number, for example, the fraction ½. The indicator is signified by the Unicode designation "No" (number, other). The value is 10.

Conclusion

Char.IsDigit:
Valid digits are members of the DecimalDigitNumber category only.
Char.IsNumber:
Valid numbers are members of the DecimalDigitNumber, LetterNumber, or OtherNumber category.

IsNumber(x) will sometimes return true for results average person would not consider to be a number and here is why.

C# groups characters into UnicodeCategory where numbers fall not into a single but 3 different categories:

UnicodeCategory.DecimalDigitNumber

Decimal digit character, that is, a character in the range 0 through 9. Signified by the Unicode designation "Nd" (number, decimal digit). The value is 8.

UnicodeCategory.OtherNumber

Number that is neither a decimal digit nor a letter number, for example, the fraction 1/2. The indicator is signified by the Unicode designation "No" (number, other). The value is 10.

UnicodeCategory.LetterNumber

Number represented by a letter, instead of a decimal digit, for example, the Roman numeral for five, which is "V". The indicator is signified by the Unicode designation "Nl" (number, letter). The value is 9.

Anything that falls in to one above will return true for IsNumber(). For is IsDigit() it will only be UnicodeCategory.DecimalDigitNumber.

I wrote this bit of code to indicate which is which: (Table isn't full due to allowed post size, but you should be able to generate it and it's only for example purposes anyway)

    [Test]
    public void IsNumberTest()
    {
        var numberLikes = new[] { UnicodeCategory.DecimalDigitNumber, UnicodeCategory.OtherNumber, UnicodeCategory.LetterNumber };
        for (var i = 0; i < 0xffff; i++)
        {
            var c = Char.ConvertFromUtf32(i).ToCharArray()[0];
            if (numberLikes.Contains(Char.GetUnicodeCategory(c)))
            {
                File.AppendAllText("IsNumberLike.txt", string.Format("{0},{1},{2},&#{3};,{4},{5}\n", i, c, Char.GetUnicodeCategory(c), i, Char.IsNumber(c), Char.IsDigit(c)));
            }
        }
    }

Result looks following: As you can see there is stuff that one would not expect to be 'number'.
