GetNumericValue(Char)
Returns the int value that the specified Unicode
character represents.
[Android.Runtime.Register("getNumericValue", "(C)I", "")]
public static int GetNumericValue (char ch);[<Android.Runtime.Register("getNumericValue", "(C)I", "")>]
static member GetNumericValue : char -> intParameters
- ch
- Char
the character to be converted.
Returns
the numeric value of the character, as a nonnegative int
value; -2 if the character has a numeric value but the value
can not be represented as a nonnegative int value;
-1 if the character has no numeric value.
- Attributes
Remarks
Returns the int value that the specified Unicode character represents. For example, the character '\u005Cu216C' (the roman numeral fifty) will return an int with a value of 50.
The letters A-Z in their uppercase ('\u005Cu0041' through '\u005Cu005A'), lowercase ('\u005Cu0061' through '\u005Cu007A'), and full width variant ('\u005CuFF21' through '\u005CuFF3A' and '\u005CuFF41' through '\u005CuFF5A') forms have numeric values from 10 through 35. This is independent of the Unicode specification, which does not assign numeric values to these char values.
If the character does not have a numeric value, then -1 is returned. If the character has a numeric value that cannot be represented as a nonnegative integer (for example, a fractional value), then -2 is returned.
<b>Note:</b> This method cannot handle supplementary characters. To support all Unicode characters, including supplementary characters, use the #getNumericValue(int) method.
