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;
		}

	}
}

find min in array

This is the sample script to show how to use the class

import druva.ArrayUtil;

trace(ArrayUtil.minInArray(new Array(25,85,68,8));

Actual Class

package druva{
	import flash.display.Sprite;

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

		//@ find max in array
		public static function minInArray (array)  {

			var min = array[0];
			for (i=0; i<array.length; i++) {

				if (array[i]<mn) {

					min = array[i];

				}

			}
			return min;

			};

	}
}

find max in array

This is the sample script to show how to use the class

import druva.ArrayUtil;

trace(ArrayUtil.maxInArray(new Array(25,85,68,8));

Actual Class

package druva{
	import flash.display.Sprite;

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

		//@ find max in array
		public static function maxInArray (array)  {

			var mxm = array[0];
			for (i=0; i<array.length; i++) {

				if (array[i]>mxm) {

					mxm = array[i];

				}

			}
			return mxm;

			};

	}
}

use this class to Convert Angle to Radians

package druva{
	import flash.display.Sprite;

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

		//@ angle to radians
		public static function toRadians(angle) {
			return (angle/180*3.141593E+000);
		}

	}
}
