GetNumericValue()
OutputVar := MfChar.GetNumericValue(c)
OutputVar := MfChar.GetNumericValue(s, index)
Converts the specified numeric Unicode character to a decimal number for c.
Converts the specified numeric Unicode character to a decimal number for the character in string s at the location of Zero-based index. Index can be instance of MfInteger or var containing integer.
c
The character to evaluate. Can be a var containing character or MfChar instance or string var containing hex value Eg:"0x0061". containing hex value such as "0x00B2" (SUPERSCRIPT TWO) or MfInteger instance.
s
The String containing the Unicode character for which to get the numeric value. Can be MfString instance or String var. Can be instance of MfString, or var containing string.
index
The index of the Unicode character for which to get the numeric value. Can be MfInteger Instance or Integer var.
Returns the numeric value associated with the specified character.-or- -1, if the specified character is not a numeric character.
Throws MfInvalidOperationException if not called as a static method.
Throws MfNotSupportedException of incorrect overload.
Throws MfArgumentOutOfRangeException is outside the range of valid indexes in s.
Throws MfArgumentException if c, s or index are object but not of the expected type.
Static Method.
The c parameter must be the Char representation of a numeric value. For example, if c is "5", the return value is 5. However, if c is "z", the return value is -1.0.
A character has an associated numeric value if and only if it is a member of one of the following UnicodeCategory categories: DecimalDigitNumber, LetterNumber, or OtherNumber.
The method assumes that c corresponds to a single linguistic character and checks whether that character can be converted to a decimal digit. However, some numbers in the Unicode standard are represented by two Char objects that form a surrogate pair. For example, the Aegean numbering system consists of code points U+10107 through U+10133.
