IsNumber()
OutputVar := MfChar.IsNumber(c)
OutputVar := MfChar.IsNumber(s, index)
Indicates whether the specified character of c is categorized as a Unicode number.
Returns true if c is a Unicode number; Otherwise, false.
Indicates whether the specified character is categorized as a Unicode number for the character at position index in s.
Returns true if the character at position index in s is a Unicode number; Otherwise, false.
c
The character to evaluate. Can be a var containing character or MfChar instance or string var containing hex value Eg:"0x0061".
c corresponds to a single linguistic character and checks whether that character represents a number. 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
s
A string. Can be a string var or MfString instance.
index
The zero-based index position of the character to evaluate in s. Can be a Integer var or MfInteger instance.
Throws MfInvalidOperationException if not called as a static method.
Throws MfArgumentOutOfRangeException if index is not in the valid range of s.
Throws MfNotSupportedException if call to method is outside its overloads.
Throws MfInvalidOperationException if not called as a static method.
Static Method.
This method determines whether a Char is of any numeric Unicode category. In addition to including digits, numbers include characters, fractions, subscripts, superscripts, Roman numerals, currency numerators, and encircled numbers. This method contrasts with the IsDigit method, which determines whether a Char is a radix-10 digit.
Valid numbers are members of the MfUnicodeCategory.DecimalDigitNumber ,MfUnicodeCategory.LetterNumber, or MfUnicodeCategory.OtherNumber category.
