Constant 'not a number' value

Can someone explain NAN to me.

I understand NULL, so you can use that in your explination if you need to. And equaly I understand Const in useage as True/False etc

Code would be appreachiated, but a nice definition and use definition would be better.

Thanks in advance

Edit: I ment to post this in the beginer area. Can Someone Move it for me

It's a special float value (there is no equivalence for integers) that denotes an invalid float number.

By example, you also have special values to denote infinity, and if you divide infinity by infinity thna you get a NaN becuse dividing infinity by infinity makes no sense and has no meaningful result.

Merci Koriolis. Comment difficile serait-il pour que mettent-ils cela dans les Docs?

No, it is not documented.
#NaN and #INF are values that are given back like this from the system itself, not a value created by BM.

Taking french courses H&K :) ?
A few mistakes but otherwise you're clearly on the right track. Or was that babelfish ;) ?

BabelFish! BabelFish! What is this Babelfish you talk of ;)

I went to a cafe had a beer left, came back with a friend and said
"Bonjour encore monsieur. Je voudrais deux bières merci"

And got a toasted ham and cheese sandwich

Babelfish is a truely craptastic translation bot on the web.

And you should not drink beer if it results in french :P
