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

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.

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

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.

most numbers in computers are represented using two's complement, which is what many of us who know are talking about converting binary to decimal. However, there is another number representation system that states all the bits except the left most are just like binary to decimal conversion and the last bit is the sign. For example, using 8 bits,

0001 1111 = +001 1111 = 32
1001 1111 = -001 1111 = -32

So...negative 0

Nothing in the last long time. Floating points.

And 12-bit implementations themselves, on the other hand, are quite common, right?
Not too hard to find. Old computers, simple PICs, and cases where the other 4 bits mean something else often do this.

And yes, Octal is completely pointless.

floating point

printf("%f", 0x80000000); // prints -0
