GetNumericValue()
OutputVar := MfCharUnicodeInfo.GetNumericValue(ch)
OutputVar := MfCharUnicodeInfo.GetNumericValue(s, index)
Converts the specified numeric Unicode character to a decimal number.
Converts the specified numeric Unicode character to a decimal number for the character in string s at the location of Zero-based index.
ch
The Unicode character for which to get the digit value. Can be instance of MfChar, A single char in a var or a string var 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.
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 MfNotSupportedException of incorrect overload.
Throws MfArgumentOutOfRangeException is outside the range of valid indexes in s.
Throws MfArgumentException if ch, s or index are object but not of the expected type.
Static Method.
The ch parameter must be the Char representation of a numeric value. For example, if ch is "5", the return value is 5. However, if ch 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.
Method assumes that ch 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.
