Vinnie's link was more pertinent than IW's

The one which might shed light is tho this one

http://en.wikipedia.org/wiki/Two%27s_complement

Drekkus, for a single byte:

you could represent positive decimal integers from 1 to 255 (2^8-1)

but, to allow for negative numbers too, you adopt for instance the "2's complement" notation

in such case you renounce to the msb, which becomes a sort of "sign bit"

01111111 = 127 (2^7-1)

10000000 = -128 (or 128-256, not 128)

10000001 = -127 (or 129-256, not 129)

you could also see it as if the 8th bit (the msb) does not count as 128 itself, but as -128

so, 127+1 "wraps" to -128

similarly, with two bytes, instead of getting up to 65535, you only use 15 bits instead of 16, and when you get to 32767 you don't increase to 32768, but you "wrap to your negative bottom" -32768 and restart up from there

I really want to understand all this, but when i see numbers in between brackets, my brain just turns off. Plus wrapping around my negative bottom doesn't help accepting this.

The computer counting integers by putting marbles into a jar.

The jar can only contain a certain amount of marbles before it's full.

There's also a special marble holder on the jar, when you put a marble in that holder it tells you that the number is negative.

So when the computer runs out of space in the jar, it puts one in the negative number holder and it suddenly thinks it's got a full jar of a negative number!

This switches it's behaviour so now every time it adds one it takes a marble out of the jar.

why would a computer want to count integers?

Vincent

Imagine your number keys on the keyboard are broken.

So you make up a list of chararcters to represent numbers

a =1

b = 2

c = 3

etc

Now you need negative numbers for a bizarre reason I do not know.

so characters a ... m are used for positive numbers, and n...z are negative numbers

n is a bit crap as the starting negative number, so lets start with a z as - 1 and count backwards.

z = -1

y = -2

x = -3

so if you start counting sheep with your broken keyboard it will be

like

a (1)

b (2)

c (3)

..

l (11)

m (12)

n (-12)

o (-11)

p (-10)

..

Old computers had unreliable numeric keypads, so the computer counts sheep with characters and lies to you.

When computers could count up to 12 it was revolutionary.

2 higher than the previous finger system, and fingers can't count negative!

Do you count 3 on each finger and not include the thumb?

http://en.wikipedia.org/wiki/Numeral_system

interesting:

Base-12 systems (duodecimal or dozenal [duodenal?]) have been popular because multiplication and division are easier than in base-10, with addition and subtraction being just as easy. Twelve is a useful base because it has many factors. It is the smallest multiple of one, two, three, four and six. There is still a special word for "dozen" and just like there is a word for 10^2, hundred, there is also a word for 12^2, gross.

did you know?

in italian, "dozzinale" (literally: "dozenly") means of low quality, ordinary, down-market, cheap.

(similar to "dime a dozen")

so, something you can get by the dozens is of little value, a dozen squared is gross!
