| Digit(Int32) |
Returnss the numeric value of a decimal digit code point. |

Returnss the numeric value of a decimal digit code point. |
Digit(Int32)
Returnss the numeric value of a decimal digit code point.
[Android.Runtime.Register("digit", "(I)I", "", ApiSince=24)]
public static int Digit (int ch);[<Android.Runtime.Register("digit", "(I)I", "", ApiSince=24)>]
static member Digit : int -> intParameters
- ch
- Int32
the code point to query
Returns
the numeric value represented by the code point, or -1 if the code point is not a decimal digit or if its value is too large for a decimal radix
- Attributes
Remarks
Returnss the numeric value of a decimal digit code point. <br>This is a convenience overload of digit(int, int) that provides a decimal radix. <br><em>Semantic Change:</em> In release 1.3.1 and prior, this treated numeric letters and other numbers as digits. This has been changed to conform to the java semantics.

Digit(Int32, Int32)
Returnss the numeric value of a decimal digit code point.
[Android.Runtime.Register("digit", "(II)I", "", ApiSince=24)]
public static int Digit (int ch, int radix);[<Android.Runtime.Register("digit", "(II)I", "", ApiSince=24)>]
static member Digit : int * int -> intParameters
- ch
- Int32
the code point to query
- radix
- Int32
the radix
Returns
the numeric value represented by the code point in the specified radix, or -1 if the code point is not a decimal digit or if its value is too large for the radix
- Attributes
Remarks
Returnss the numeric value of a decimal digit code point. <br>This method observes the semantics of java.lang.Character.digit(). Note that this will return positive values for code points for which isDigit returns false, just like java.lang.Character. <br><em>Semantic Change:</em> In release 1.3.1 and prior, this did not treat the European letters as having a digit value, and also treated numeric letters and other numbers as digits. This has been changed to conform to the java semantics. <br>A code point is a valid digit if and only if: <ul> <li>ch is a decimal digit or one of the european letters, and <li>the value of ch is less than the specified radix. </ul>
