  Good catch. I didn't even notice this while reading the grandparent comment. But I've seen people debate this fact, or rather the fact that 0.9̅=1, for days and weeks on the internet.

  Wow, you just pushed me and my girlfriend into a heated debate regarding this. Is there a list anywhere of similar unintuitive math properties/facts?
