NaN

[YoBro]

How can I check if a number is NaN?
if(nNumber == NaN){ } just doesn't work.

How can I check if a number is NotaNumber?

Does not compute.

You could try: if(nNumber == "NaN"){ } (putting the NaN in quotes)?
Or: if(nNumber == undefined){ } (using undefined)

Hopefully one of those two methods work.

Why you would want to check if a number is not a number?

Because I use String.charCodeAt(); and I want to check if it returns NaN or not.

Lol, got it to work.
if(nNumber != Number){ }

Would that really work correctly?
You should use typeOf nNumber
trace(typeOf nNumber) would trace 'number'.

Why do you write with capitals?

Sorry, I just sometimes get upset when a proplem with an easy answer takes so many people to figure out.

And I made a typo: It should be isNaN(), not isNan().

try not to get upset. just because you knew the answer 8 replies back doesnt mean everyone else did. in fact, they clearly didnt, since they were offering replies that were just attempted workarounds. if that is what it takes to make you upset, you should just leave before you ever get to 100 posts.

your help, though appreciated, is not required around here. if these fora are going to negatively affect your blood pressure, do everyone a favor and just disconnect your computer from the wall.
