[removed] Ordinal suffix for numbers with specific CSS class

Question

I am trying to display numbers within a particular table with ordinal suffixes. The table always shows three numbers which come from an XML file. The numbers show ranks, so for

Answer 1

I created two approaches one using Prototype, the other as a plugin :

Number.prototype.between = function(n,m){ return this > n && this < m }
Number.prototype.ORDINATE_INDEX = ["th","st","nd","rd"];
Number.prototype.toOrdinate = function(){
    var
        nthMod = (this % 10),
        index =  nthMod > 3 || this.between(10,20) ? 0 : nthMod
    ;

    return this + this.ORDINATE_INDEX[index];
};

$(".ordinal").text(function (index, element) {
    return parseInt(element).toOrdinate();
});

This is the one as a Jquery Plugin :

(function($){
    var numberTool = new (function(){
        var private = {};

        private.ORDINATE_INDEX = ["th","st","nd","rd"];

        private.parseOrdinary = function(number)
        {
            var
                nthMod = (number % 10),
                index =  nthMod > 3 || private.between(number, 10,20) ? 0 : nthMod
            ;

            return number + private.ORDINATE_INDEX[index];
        }

        private.between = function(number, n,m){
            return number > n && number < m
        }

        this.isNumeric = function(number)
        {
            return !isNaN(parseFloat(number)) && isFinite(number);
        }

        this.toOrdinary = function(number)
        {
            return this.isNumeric(number) ? private.parseOrdinary(number) : number;
        }
    });


    $.fn.toOrdinary = function(){
        return this.each(function(){
            $element = $(this);
            $element.text(numberTool.toOrdinary($element.text()));
        }); 
    };
})(jQuery);

$(".ordinal").toOrdinary();
$(".ordinal").toOrdinary();
$(".ordinal").toOrdinary();
