Okay so for the most part I've been advoiding this cause it dont make sense 000000000000000000000000001 something like that. Any place that explains an decodes binary? College stuff an sorts.
-
Lot of stuff on the web ....... plenty.
I have a page on one of my sites which might help you if you are starting off - just explanatory stuff and with a bias toward colors and binary/hex.
Take a peek (http://www.alumbankweb.com/img_matters/basefile/bin_hex.htm) if it might help.

It gives me a basic knowdlge I knew some of that.

Why doesn't it make sense?
000000000000000000000000001
is a number in binary. What don't you understand? You understand 125 or 62 or 3419 don't you, and they are numbers.
-
there simplifed numbers not base 2 or 6 8, 10003
-

Fair enough but you were not specific.! Original question is a bit vague.
"Simplified numbers"! - well those are base 10 that's all - same as binary might be base 2, 8, 16 etc.
I think if decoding is what you are after, a web search will work - or use a hand held calculator with that function.
-
i dont know could be wrong on my part

I always have great trouble understanding squall's questions.

Binary:
1 = 1
10 = 2
11 = 3
...
go from right to left adding 2 to the power of the position to a running total. This wil give you the decimal equivalent.
Unless your actually talking about Machine code, which is somewhat dumb to learn ever. ASM would be beneficial, especially on account of not actually being able to see the binary representation of any executables.
I always have great trouble understanding squall's questions.
It's a very non-exclusive club. The main confuser for me was "decodes binary" you don't decode binary, so that kind of made the whole question ambiguous. I'm sure we'll discover the actual intended question around page 7.
-
I take "decodes binary" as conversion from binary/hex to decimal. :)
-
aside from the fact that it isn't Decoding but rather a simple base conversion.

1 = 1
10 = 2
11 = 3
go from right to left adding 2 to the power of the position to a running total. This wil give you the decimal equivalent.
Thats what I'm looking for, however someone with more math understanding then I can say its easy. should 11=4 since its based 2 ? It just seems logical to me. I understand a little better at any chance so 101 is six?
-
00001 00010 00100 01000 10000
1 2 4 8 16
Sort of like this. I can explain it well on paper.
Look at the link I gave you and click on the numbers 1, 2, 4, 7, 16. What do you notice about the hand?
-
four represented is bad an that the numbers clicked move with the hand sigh?

I dont get what your tring to show me but thats what I understand out of it.

Lol, I'm confusing myself. :-[
I'm sure Google and Wikipedia have a lot to say.

101 = 6 (look at my link for number 5)

the ones place is power 0, that is, 1 binary is still 1 decimal.
Now we're getting Somewhere- 11 in binary is 3 decimal, because we have 2 to the power of 1 + 2 to the power of 0. with is 2 and 1 (any number to the power of 0 is 1) respectively.
personally I've just done the power method myself- important thing I should have mentioned was starting at 0 for the exponent.
so 101 binary is
2^0+2^2, or, 1+4, or 5.
I hope this makes sense....
-
in both base 10, and base 2 (binary) the place of the digit matters, and it works like this
base 10
1000's 100's 10's 1's
5 3 2 4
That number is 5 x 1000, 3 x 100, 2 x 10, and 4 x 1.
Binary is the same idea only you go up in powers of 2 not 10
128's 64's 32's 16's 8's 4's 2's 1's
1 0 1 1 0 1 1 1
That number equals 1 x 128 plus 1 x 32 plus 1 x 16 plus 1 x 4 plus 1 x 2 plus 1 x 1.
Squall, can you work it out?

I hate to tell you but 2+2+2+0 isnt 5

More squall crazy nonsense ::) Read it again.
-
how can that be?????? Five is zero unless its valued at one. Its ether on or off so which is it? Cause this up arrow means that there being added to me.
-
All I can suggest - in hopes things clarify - is once again go check my page (http://www.alumbankweb.com/img_matters/basefile/bin_hex.htm) on bin and hex!
Seems an interpretation problem here! :)
-
I have it or did save it again an will read latter.
-

It doesn't mean that.
-
so multiply? that explains why my answer is wrong.
-
2^2 means "two raised to the power of two".
-
2^2 means "two raised to the power of two".
...Which means 2 x 2 = 4.
3^3 = 27, because 3 x 3 = 9, 9 x 3 = 27.
-
but there are three two's?

There are three figure twos that you can see, yes.
2^0+2^2
Remember I already explained that the up arrow ^ means "to the power of". If you don't know what that means, you have some studying to do before you can deal with binary arithmetic.
If you read it out loud, it says "two to the power of zero plus two to the power of two".
Two to the power of zero equals one.
Two to the power of two equals four.
Four plus one equals five.
I think I can tell you are having a hard time understanding all this. I suggest you do the following:
1. Get a good math or computer science book that deals with binary arithmetic.
2. talk to your teacher.
Forums like this are not the best way to tackle this sort of learning project.

Five is zero unless its valued at one.
That doesn't make sense in any context.
5=1 ? 5 : 0
Nope, conditional doesn't believe you.
but there are three two's?
Indeed- but we must also focus on the operators(or lack thereof) between those 2's. Just as 222 isn't 6, 2^2+2^0 isn't 6 either.
Defaulting to addition with operators your unfamiliar with is sure to give incorrect results.
-
Just occurred to me that one aspect that might cause confusion for some is - base two to power zero - the 2^0 aspect, is being seen as actual 2 decimal, when in fact in binary, representation of the value is of course 1, just in that first position.
Higher positions of course have to be either 0 or a true power of 2 - according to the hierarchy of position ..... powers of base 2 from 1 thru 7.
Thus - 2^1 or zero for position 2, 2^2 or zero for position 3, 2^3 or zero for position 4 .. and so on.
It's always works remembering binary is analagous to switching or truth - only two possible states at each level - "on"/"off" or "True"/"False"
Probably doesn't help much!
-
It helped explain that problem. I understand it better.

In fact, any number to the power zero equals 1.
There is a simple (ish) explanation of why this is so here (http://mathforum.org/library/drmath/view/55892.html)
Extract:
if you divide a number to a power by the same number to a different power, the answer is the
same number raised to the difference of the first two powers.
For example,
3
2 (3-2) 1
---- = 2 = 2
2
2
What happens when the powers in the numerator and denominator are the
same?
3
2 (3-3) 0
---- = 2 = 2
3
2
But you know that 8/8 = 1. So 2^0 must equal 1.

I understood his, but yours has more details.

Useful stuff Dias ... :)

heres the thing he said that we dont need to understand this.

Who said that? ::) understand what? Why revive this 6 week old thread?

my pc arc teacher. Binary, cause he told us that we didnt have too...

Excuse me. I am confused. Who said you "have" to understand binary arithmetic? Anyway it's not hard. You either have a one, or you don't. If you do, that's called a one. If you don't, that's called a zero. That's all there is to it. Now go haul out the trash, or you don't get no spending cash!
-
i understand it better, but thought he had wanted us too
-
he's saing that we had too but i got a complete understanding an able to do it know.
-
What just happened this thread? ::)
-
he says one thing an then another the important thing is I got it.

No cover.

What just happened this thread? ::)
It died, and Squall decided to revive it because everybody was starting to turn purple from holding their breath.
-
Just letting you know what has happened. Is that so bad?
-
How old are you, Squall?
-
Just letting you know what has happened. Is that so bad?
Ummm....I don't know about anyone else, but I still don't know what happened. ???
-
Ummm....I don't know about anyone else, but I still don't know what happened. ???
It's very easy to understand - Squall and Nymph have been swapping ideas ;D :D

20 If you recall theres a post about it. No I dont even now whom that is.
