Thanks Boom!

The first one won't open . . . but I'll have a play with the second (if those pop-ups stop interfering)

How are you with Fermat's Last theorem? . . . and BTW have you read "The Music of the Primes" by Marcus du Sautoy ?

Hi Phoenix,

Both links work, as I have downloaded both prior to posting them...

I haven't read these 2 books, as I left my scientific studies behind...

O my god, and some people say i talk too much.
I need to know hoto to calulate NEGATIVE decimal to binary one on hand, by head or whatever it is in english.
Here i did not see any normal answer and it came from one of my classmates - just convert the decimal as if it was a plus and after that replace all 1 with 0 and 0 with 1.
So if we have 110010 for 100 with -100 we have 1001101 add 00000001 and -100 = 1001110.
Cheers.
Now i would dare to ask how we multiplex with heximals:)

Something tells me that both you and your classmate are going to fail this subject because you ain't listening...

+100 = 1100100

-100 = 11100100

Well I did not see a simple explanation like mine in order to understand it.I mean what the hell this means:

Hey GR I think the guy wants you to write him the whole program of dividing by twos...

Just a question though. How can someone tell if a given binary contains the MSB or not?
I mean without knowing this in advance one would think like that
111010=+58
0111010=+58
1111010=+122 not -58


You've only used up 7 bits Pyro, you forgot one bit!

I started off the theory for Acunga with the simplest 8-bit system that works for numbers between -128..127.

Here's a handy table to clear things up...

Name.................. Size.........Range
Byte.....................8-bit.......-128..127
Word....................16-bit......-32768..32767
Double Word.........32-bit......-2147483648..2147483647

Regards, GR.

In case you didn't understand...

Just tell the rule, no need to make it more complex and loong.No ofence just try to help with the help in the forum

Negative Numbers In Binary :


Negatives:
Two’s complement system
Same as sign-magnitude for positives
With N bit numbers, to compute negative
Invert all the bits
Add 1
Example: -25 in 8-bit two’s complement
25 « 00011001
Invert bits: 11100110
Add 1: 1
11100111

Negatives:
Sign-Magnitude system
With a fixed number of bits, say N
The leftmost bit is used to give the sign
0 for positive number
1 for negative number
The other N-1 bits are for the magnitude
Example: -25 with 8 bit numbers
Sign: 1 since negative
Magnitude: 11001 for 25
8-bit result: 10011001
Note: This would be 153 as a positive.

[B&N SERVICES]

As I still remember, when for example computer is working on a binary numbers, first digit is always reserved for "plus" or "minus", where "0" means plus and "1' means minus
That's all...

I'd ask Mr Quamersland, he'll probably look it up in the Koran and give you the answer.

Half past two!
