InheritanceRangeError Inheritance Error Inheritance Object

A RangeError exception is thrown when a numeric value is outside the acceptable range. When working with arrays, referring to an index position of an array item that does not exist will throw a RangeError exception. Using Number.toExponential(), Number.toPrecision(), and Number.toFixed() methods will throw a RangeError exception in cases where the arguments are outside the acceptable range of numbers. You can extend Number.toExponential(), Number.toPrecision(), and Number.toFixed() to avoid throwing a RangeError.

The following example shows how a RangeError exception can be generated and handled within a try..catch statement. 
package {
    import flash.display.Sprite;

    public class RangeErrorExample extends Sprite {

        public function RangeErrorExample() {
            var child:Sprite = new Sprite();
            try {
                addChildAt(child, 1);
            }
            catch(e:RangeError) {
                trace(e);
            }
