Language Version:

Runtime Versions:

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.

Other situations that cause this exception to be thrown include the following:

• Any Flash Player API that expects a depth number is invoked with an invalid depth number.
• Any Flash Player API that expects a frame number is invoked with an invalid frame number.
• Any Flash Player API that expects a layer number is invoked with an invalid layer number.
