This list has two functions already for arabic-to-roman number conversion (RomanNumberal_1to4K(Parameter_number) by Brad Lowry, and RomanNumerals ( PageNumber ) by Don Wieland); this function performs the inverse operation. GetAsArabic( romanNumber ) returns the arabic number equivalent to romanNumber [a text string representing a roman numeral]. It will return correct values for both correctly and incorrectly formed roman numberals, and ignore all characters other than �i�, �v�, �x�, �l�, �c�, �d�, and �m�.
