Who/what uses that system? |

For example, using 8 bits, 0001 1111 = +001 1111 = 32 1001 1111 = -001 1111 = -32 So...negative 0 |

Hahaha, that was awesome. The worst part about that is the fact that it made me remember I have almost the same conversations like that. Except in real life. People that don't get the jokes should stay away, instead of making it less enjoyable for people who do. |

XFD @ this thread. |

That actually makes sense, but only if you already knew it... So yeah. |

I got the joke. xD
The octal number system is rather odd yeah, I yet have to use it. xD Anyone who ever played around with SMB bugs knows that when you hit 128 lives, you actually hit -128 due to overflow (and whenever you die, it's a game over due to the negative number). From 0111 1111 to 1000 0000. And the first byte is a "signed" byte and uhm... i'm not sure how negative numbers are calculated though, so don't ask me. 
Drat, it's hard to explain. Though, it should be said. Overflow exists everywhere. This post made so much sense that it made negative sense. |

Wow, geek humor. |

This is either as funny as the "jokes" about pi, or I just plain don't get it. |

Originally posted by Danielle Well, same...here. I´m not into hex stuff. "You know, maybe it was so hilarious, that it hit negative hilarity." Yeah, what he sid. |

Originally posted by neotransotaku In my microcontroller class a while back, the dude was talking about what symbol means what base, i.e. binary, hex, base ten, and octal. His side note for octal was "This isn't used in this class, nor anywhere in the real world" |

800 could also be negative zero... |

You know, if you had negative weight, you'd have negative mass.
And if you had negative mass, you'd have negative gravity. How do you type Alastor? |
| HyperHacker Posts: 942/5072 |
I get it, but this seems completely incorrect. 000-7FF are positive, and 800-FFF are negative. FFF is -1, FFE is -2, etc. At least in every signed integer implementation I've ever heard of. Once you got to 800 you'd be -2048 pounds. And shoot off into the sky. |
