The below code shows how to use the class

import druva.NumberUtil;

trace(NumberUtil.ordinalise(1));//  1st
trace(NumberUtil.ordinalise(2));//  2nd
trace(NumberUtil.ordinalise(3));//  3rd
trace(NumberUtil.ordinalise(4));//  4th
trace(NumberUtil.ordinalise(111));//  3rd
trace(NumberUtil.ordinalise(113));//  4th

This is the actual class for validation

package druva{
	import flash.display.Sprite;

	public class NumberUtil extends Sprite {
		public function NumberUtil() {
		}

		public static function ordinalise(number:Number):String {
			var numS:String=String(number);
			var suffix:String;
			if (numS.substr(-2,2)!="13"&&numS.substr(-2,2)!="12"&&numS.substr(-2,2)!="11") {
				if (numS.substr(-1,1)=="1") {
					suffix="st";
				} else if (numS.substr(-1, 1) == "2") {
					suffix="nd";
				} else if (numS.substr(-1, 1) == "3") {
					suffix="rd";
				}
			}
			if (! suffix) {
				suffix ="th";
			}
			return numS+suffix;
		}

	}
}

in as3 trace you can pass multiple values without using ‘+’ operator

var a =1;
var b=2;
var c = 3;

trace(a, b, c);
//ouput 1 2 3

The below code shows how to use the class

import druva.NumberUtil;
trace(NumberUtil.isBetween(5, 10,100));
// 10

trace(NumberUtil.isBetween(5, 10,100, 50));
// 50

This is the actual class for validation

package druva{
	import flash.display.Sprite;

	public class NumberUtil extends Sprite {
		public function NumberUtil() {
		}

		public static function isBetween(number:Number, min:Number, max:Number, def:Number=0):Number {
				return ((number >= min ) && (number <= max )) ? number : ((def == 0) ? min : def);
		}

	}
}

The below code shows how to use the class

import druva.NumberUtil;

trace('500 ', NumberUtil.formatterC3(987654321));
// 987,654,321
trace('489 ',NumberUtil.formatterC3(123456789));
// 123,456,789
trace('5 > ',NumberUtil.formatterC3(111222333));
// 111,222,333
trace('1 > ',NumberUtil.formatterC3(556677));
// 556, 677

This is the actual class for validation

package druva{
	import flash.display.Sprite;

	public class NumberUtil extends Sprite {
		public function NumberUtil() {
		}

		public static function formatterC3(number:Number):String {
			//C3 - comma for 3 digits
			var numS:String=String(number);
			if (numS.length>3) {
				var n:Number=numS.length%3;
				var output:String=numS.substr(0,n);
				for (var i:Number = n; i<numS.length; i += 3) {
					output += ((n == 0 && i == 0) ? "" : ",")+numS.substr(i, 3);
				}
				return output;
			}
			return numS;
		}
