Not a Number

Good price.

You ever have one of those moments when you just put 2 and 2 together, and also that you should have had that realization many years ago?
I just realized what NaN stands for...
This must be what people who get told "you can just wait for the shower water to warm up before hopping in" feel like.
- The elephant and rope parable rings its bell of sound morals!
  Not so much the realizing what NaN means; that's more relevant to that XKCD which I probably don't need to describe here.

"That makes it free, right?"
- Not only that, it makes your entire purchase free due to NaN arithmetic.
  
  But as you mention, NaN propagates.
  \ So at checkout, your wallet will become NaN, as the shops money balance. Then it will spread to your bank account and before you realize what happens the whole banking-district is in flames.
  
  no, it costs NaN, now remove NaN from your account...
  ...oh no
- Technically it has a pricetag, so...

0*(NaN)... So does that mean the price IS a number?
- Isn't any math operation involving NaNs also a NaN? At least that's my gut feeling.
  
  Based on my frequent exploding and vanishing gradients, that would be a yes.
  
  Good point.
- I suppressed most of my former js knowledge but I guess it's a string now.
  
  Javascript carcinization.
- In JS, it's just NaN if my browser's console is to be believed. I suspected it would probably be {object} for no clear reason
  
  for no clear reason
  JS That's the reason. The language has an awful type system.
- If 0/0 is NaN, then does that mean 0NaN = 00/0 = 0?
- 0*NaN = NaN

dirty onanists spilling their seed
- Lennin died, with him died lenninism. Stalin died, with him died stalinism. Grandpa Onan, don't die!
  
  What is spilled cannot die

ONaN
- In my language, onanování is masturbating. And onan is a mild insult insinuating that someone wanks a lot.
  
  It's onanism in English. And it's rather stupid to call it that because Onan didn't masturbate, he used the pull out method to avoid getting his sister-in-law pregnant with his brother's kid. (yes, I know that sounds weird but that's the story)
  
  Onanieren in German
  
  Onani in Swedish, which this image is from.

  by Mark Twain, btw. short read, and hilarious
- ...spilled his arithmetic overflow on the ground.

I like how the code adds a 0 at the start.
- The code probably checks if the following number is greater than 10 (which fails for NaN) and otherwise adds a 0 in front.

It's priceless

Onani!

cost = "arm" + "leg";
