AS3 Tip of the Day

So it appears DataType Number cannot be tested against null conditions. In order to determine if a Number has no value you must use the function isNaN(num) which returns a Boolean. That’s right boys & girls a Numbers initial value is Not a Number ;-) Oh AS3 you confound me!

  1. Wow that’s pretty wierd but I guess it makes sense since everything else is null when you first initialize it. Still that is some good info to know.

    Thanks for the tip as usual.

  4. Also, to set an argument of datatype Number (and you do not want a default of a Number) use NaN as well.
