IsDigit()
OutputVar := MfChar.IsDigit(c)
OutputVar := MfChar.IsDigit(s, index)
Indicates whether the specified character of c is categorized as a decimal digit.
Returns true if c is a decimal digit; Otherwise, false.
Indicates whether the specified character is categorized as a decimal digit for the character at position index in s.
Returns true if the character at position index in s is a decimal digit; 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 Unicode character.
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 MfChar is a radix-10 digit. This contrasts with IsNumber, which determines whether a Char is of any numeric Unicode category. Numbers include characters such as fractions, subscripts, superscripts, Roman numerals, currency numerators, encircled numbers, and script-specific digits.
