I want to add the value for 16 input and 1 output by input and output has 16 bit length. I have 2 types of the input value. Binary 16 bit for positive value and sign bit is '0' such as "0111000101111000" for (29048). 2's complement 16 bit for negative value and sign bit is '1' such as "1000111010001000" for (-29048). The Binary Option method of 3’s. If you are into numerology, or believe in Fibonacci numbers, or understand Pi, then this might be a great system for you. On the other side, if you are an investor looking for lucky number, then 3 just became that number. The bottom line is if you want to succeed at trading binary options and make profits you need to have a system and a method. This method was developed with some associates at iOption. com   Too many experienced and novice investors confuse binary options with forex options, there are many differences, but the most important difference, is that binary option trading are for very short periods of time, and you never actually own anything, you are simply renting the rights to an asset. Once you understand the difference and change your mindset you can make huge profits. Think of it as the difference between rents a house, buying a house or leasing a house with an option to buy.

When you rent a house, you are paying for the use of the house during a specific time frame, and you have no benefit from the market value or the equity. When you are trading stock options or future options you are leasing a house with an option to buy at a specific price. With time you will be able to develop or adjust your trading method to make profits, but if you would like to try an all new method, the 3-3-3 is one of the best for binary options. You will find that binary options are an easy and highly profit investment vehicle to trade the economic calendar, economic events listed on the calendar have direct actions in the markets when the data is released. You can easily find an economic calendar to see which events are scheduled to be announce. An economics calenda r gives the user 3 important pieces of information. The economics calendar also provides a lot more information, the name of the event, the time of the release and the currency likely to be effected by the results. Most economic calendars also rank the events by the importance or effects on the markets. 3)      Little market value except it helps develop a complete view of the economy or supports other reports. It is important to select only very important economic reports, those listed with 3 stars or however your calendar shows that they are important. Once you have selected the event you would like to trade, you need to have 3 choices again. You need to remember forecast has nothing to do with good or bad, it is what economist and analysts are expecting the report to show.

If for instance the jobs market is bad and the report forecasts a loss of 200,000 jobs, that is bad for the economy, but if the report comes in and shows that the economy only lost 180,000 jobs, that is above forecast and is good for the currency as traders have already figured in the forecasted data and the markets have adjusted. You then have to select the asset you are going to trade. Here you have 3 choices. 2)      A commodity such as gold or oil, which could also be effected by the report. For instance a drop in GDP will usually cause a drop in oil. Lower growth, lower demands for oil. 3)      An index or stock that might be affected by the report. If interest rates are dropped perhaps a home builder or bank stock could be a better trade. Once you have selected the vehicle for your trade you have once again 3 choices. The Binary Option method of 3's. Once you have determined which way the asset or security you are analyzing will go you have the possibility of 3 results.

Once you have selected you made all your decision and are ready to wait for the release of the economic report, you can now learn to implement the final method of the 3's.  The views and opinions expressed herein are the views and opinions of the author and do not necessarily reflect those of NASDAQ, Inc.

I saw a buggy code in C which was used to check whether addition results in overflow or not. It works fine with char , but gives incorrect answer when arguments are int and I couldn't figure why . Here's the code with short arguments. This version works fine, problem arise when you change arguments to int ( you can check it with INT_MAX ) Can you see what's wrong in here ? Because in 2s complement, the integers can be arranged into a circle (in the sense of modulo arithmetic). Adding y and then subtracting y always gets you back where you started (undefined behaviour notwithstanding). In your code, the addition does not overflow unless int is the same size as short . Due to default promotions, x+y is performed on the values of x and y promoted to int , and then the result is truncated to short in an implementation-defined manner. Why not do simply: return x+y<=SHRT_MAX && x+y>=SHRT_MIN In C programming language, signed integers when converted to smaller signed integers, say char (for the sake of simplicity), are of implementation-defined manner.

Even though many systems and programmers assume wrap-around overflow, it is not a standard. So what is wrap-around overflow? Wrap-around overflow in Two's complement systems happens such that when a value can no longer be presented in the current type, it warps around the highest or lowest number that can be presented. So what does this mean? Take a look. In signed char, the highest value that can be presented is 127 and the lowest is -128. Then what happens when we do: "char i = 128", is that the value stored in i becomes -128. Because the value was larger than the signed integral type, it wrapped around the lowest value, and if it was "char i = 129", then i will contain -127. Can you see it? Whenever an end reaches its maximum, it wraps around the other end (sign). Vice versa, if "char i = -129", then i will contain 127, and if it is "char i = -130", it will contain 126, because it reached its maximum and wrapped around the highest value.

(highest) 127, 126, 125, . , -126, -127, -128 (lowest) If the value is very large, it keeps wrapping around until it reaches a value that can be represented in its range. UPDATE: the reason why int doesn't work in oppose to char and short is because that when both numbers are added there is a possibility of overflow (regardless of being int , short , or char , while not forgetting integral promotion), but because "short" and char are with smaller sizes than int and because they are promoted to int in expressions, they are represented again without truncation in this line: So any overflow is detected as explained later in detail, but when with int , it is not promoted to anything, so overflow will happen. For instance, if I do INT_MAX+1 , then the result is INT_MIN, and if I tested for overflow by INT_MIN-1 == INT_MAX, the the result is TRUE! This is because "short" and char get promoted to int, evaluated, and then get truncated (overflowed). However, int get overflowed first and then evaluated, because they are not promoted to a larger size. Think of char type without promotion, and try to make overflows and check them using the illustration above. You will find it that adding or subtracting values that cause the overflow returns you to where you were. However, this is not what happens in C, because char and "short" are promoted to int, thus overflow is detected, which is not true in int, because it is note promoted to a larger size. For your question, I checked your code in MinGW and Ubuntu 12.04, seems to work fine. I found later that the code works actually in systems where short is smaller than int, and when values don't exceed int range. This line: is true, because "sum-x" and "y" are evaluated as (int) so no wrap-around happens to, where it happened in the previous line (when assigned): Here is a test.

If I entered 32767 for the first and 2 for the second, then when: sum will contain -32767, because of the wrap-around. However, when: "sum-x" (-32767 - 32767) will only be equal to y (2) (then buggy) if wrap-round occurs, but because of integral promotion, it never happen that way and "sum-x" value becomes -65534 which is not equal to y, which then leads to a correct detection. Here is the code I used: You need to provide the architecture you are working on, and what are the experimental values you tested, because not everyone faces what you say, and because of the implementation-defined nature of your question. Reference: C99 6.3.1.3 here, and GNU C Manual here. The compiler probably just replaces all calls to this expression with 1 because it's true in every case. The optimizing routine will perform copy propagation on sum and get. It's true in every case because signed integer overflow is undefined behavior - hence, the compiler is free to guarantee that x+y-y == x and y+x-x == y. If this was an unsigned operation it would fail similarly - since overflow is just performed as a modulo operation it is fairly easy to prove that. - PowerPoint PPT Presentation. 1’s and 2’s complement.

What are advantages of Two's Complement? In some ADCDAC devices their are options to outputinput the data in 2's Complement form. What are advantages of representing digital data in Two's Complement form When you can simply have straight binary code and save time of conversion? Two's compliment representation of signed integers is easy to manipulate in hardware. For example, negation (i. e. x = - x ) can be performed simply by flipping all the bits in the number and adding one. Performing the same operation in raw binary (e. g. with a sign bit) usually involves a lot more work, because you must treat certain bits in the stream as special. Same goes for addition - the add operation for negative numbers is identical to the add operation for positive numbers, so no additional logic (no pun intended) is required to handle the negative case. While this doesn't mean it's easier from your perspective, as a consumer of this data, it does lessen the design effort and complexity of the device, thus presumably making it cheaper. The ADC can convert data (say input voltages between 0 and 5V) and you either need that data to be unsigned (0V=0, 5V=max code) or signed (2.5V=0, 0V=max - ve, 5V=max +ve). In addition to 2's complement being the commonest computer representation for signed data, the conversion between the two formats described above is completely trivial : simply invert the MSB! This is incredibly cheap to add to the ADC's internal logic and gives the ADC another selling point on the datasheet. If you need to perform math on the representations of negative numbers, twos complement makes that easier than offset binary, which will match with the "signed int" data type. Your compiler will simply know how to deal with it. Otherwise, you spend clock ticks converting back and forth. In the question, it seems to be implied that it takes longer for the ADC to return the value in 2's complement form than in straight binary.

While this might be the case in some particular implementation of an ADC, it's not true in general (for example the MSP430 series of micro-controllers have an ADC peripheral on-chip which will report the value in straight binary or 2's complement, but it takes the same number of cycles in both cases). With that out of the way, the choice between 2's complement and straight binary mostly comes down to how your transducers work and how you like to process your data. In straight binary mode, the ADC is giving you a number which represents the ratio between the magnitude of the analog quantity measured (virtually always voltage) and the full-scale reference quantity. For example, a 10-bit ADC can return values from 0 to 1023 (inclusive). If you measure a voltage (say, 1.25 Volts) which is half of the ADC's reference voltage (say, 2.50 Volts), the binary code you read will be half of the maximum value you could read--so, 512, or thereabouts, subject to rounding and non-linearities in the ADC. For example, let's say you have a transducer which reports the amount of rocket fuel in a tank. 0V means the tank is empty and 2.5V Volts means it's full. So you just connect the transducer to your ADC, and away you go! But notice that in the above paragraph, there's no way to measure negative voltages. What if we wanted to measure the flow of rocket fuel in and out of the tank (and we had a transducer to do so)? The ADC can't measure negative numbers, so we have a problem. However, there's an easy way to fake it using 2's complement mode: In this case, the transducer output is re-biased so that the zero point is halfway between the ADC's two reference voltages. In other words, positive flows are represented by voltages between 1.25V and 2.50V, and negative flows are represented by 1.25V to 0V--so flows into the tank will give ADC codes of 512 to 1023 and flows out of the thank will give codes of 511 to 0 (in straight binary format). Now that's awfully inconvenient. We have to subtract 512 from each measurement before doing anything with it, which gives numbers in the range -512 to +511. The point of 2's complement mode is that it does this for you!

However, you still might want to use straight binary with a transducer that produces signed results. For example, your transducer might have differential outputs: In this case you'd want to subtract the inverted output from the non-inverted output anyway, so there's no advantage to using 2's complement. The two's complement system is in use, because it stems from how simple hardware naturally operates. Think for example you car's odometer, which you have resetted to zero. Then put the gear on reverse, and drive backwards for 1 mile (Please don't do this in reality). Your odometer (if it's mechanical) will roll from 0000 to 9999. The two's complement system behaves similarly. Please note that I'm not really offering any new information here, just the odometer example which someone might find helpful - it helped me to understand the rationale of two's complement system when I was young. After that, it was easy for me to intuitively accept that adders, subtractors etc work well with the two's complement system. And yes, my Nissan's odometer does work this way. Others have already answered why twos compliment binary is convenient for computer hardware. However, you seem to be asking why a AD would output twos compliment instead of "straight binary" (whatever you think that really means).

Most ADs do output a simple unsigned binary value ranging from 0 to 2 N -1, where N is the number of bits the AD converts to. Note that this could also be considered twos compliment notation, just that the values never happen to be negative. If you are only dealing with positive numbers, then most binary representations are the same. This includes twos compliment and sign magnitude. Some ADs, particularly those built into microcontrollers, have the option of producing negative values for the lower half of their range. This can be a perceived advantage when measuring a bipolar signal. At least in a microcontroller, this is generally silly. In some cases you might use the AD values directly without any conversion. In that case, you have already converted all the other values to the AD range. Restricting that to all non-negative numbers actually simplifies things. Otherwise, you are going to apply some scaling and offset to the AD readings anyway to get them into whatever units you use for values internally. Here again there is no downside to unsigned values coming directly out of the AD. In fact, I usually apply some low pass filtering on the raw values before any scaling and offset. Knowing those values will never be negative simplifies the computations slightly. Doing the scaling on unsigned values also makes things a little simpler sometimes.

I can't remember a single case in well over 100 microcontroller projects where I used the AD in anything but unsigned output format. So to answer the question of what the advantages are of a AD outputting "twos compliment", there are two answers: They all do anyway, just that most of the time these values are non-negative, so you can't tell the difference between twos compliment and other notations, like sign magnitude. The advantages are very slight. Inside a microcontroller they are essentially non-existent. In dedicated hardware, there can be some advantage to have negative values indicating negative input voltage, in which case twos compliment is the easiest way to deal with the range of values. Note that if the input voltage range isn't symmetric about 0, then this advantage goes away. What is this 'straight binary code' you speak of? I assume you mean having a sign bit which is '1' for negative and '0' for positive (or vice-versa ). This has two more disadvantages over twos complement which have not yet been mentioned: one largely irrelevant these days and one important. The largely irrelevant one is that you can represent one less number - i. e. 255 numbers in 8 bits. This is pretty irrelevant when you've got 32 or 64 bits but mattered when you had as few 4 or 6 bits to work with. The more important one is that there are now two ways to represent the same number - specifically, 0 - +0 and -0 but +0 and -0 are the same number so your implementation needs to make sure that you're not comparing these numbers every time you do an equality check.

How to binary trade 2's complement Hi pinball. First of, welcome to GIDForums™. I remember reviewing 2's complements in another topic a while back. Unfortunately, this thread only explains what 2's complement is and doesn't provide a C code for it. If no one else responds with something, I will see if I can code up that explanation. That should be it. Here is a little test program that takes a twos compliment the hard way and the easy way: As far as displaying your number as a decimal, it should be real easy with the printf command. Just tell printf command what you want to display. There is no conversion. The most popular tutorials on GIDForums™ discusses this. We get alot of people looking for answers how to "convert" from decimal to binary to hexidecimal etc.

The quick answer is there is no need to. 1's complement = 010101111. 2's complement = 010110000 = B0h or 176d. 1's complement = 010101111. 2's complement = 010110000 = B0h or 176d. haha! I think I see what the problem is (potentially). The twos compliment is going to switch every bit of your number. The twos compliment is: 1111111010110000 (FEB0). So I guess the question is: what size of data are you working with? 336 does not fit into 2-bytes. The twos compliment is: 1111111010110000 (FEB0). So I guess the question is: what size of data are you working with? 336 does not fit into 2-bytes. Ahh yes, it makes sense now.

It was all the leading 1's that were throwing off my number. I think I know how to take care of that but I'll have to do some more testing. tics meaning blood sucking parasites.

There is no 2, 3, 4, 5, 6, 7, 8 or 9 in Binary! A " bit " is a single b inary dig it . The number above has 6 bits. Binary numbers have many uses in mathematics and beyond. In fact the digital world uses binary digits. How do we Count using Binary? The same thing is done in binary . And that is what we do in binary . . but that number is already at 1 so it also goes back to 0 . . and 1 is added to the next position on the left. add 1 on the left. See how it is done in this little demonstration (press play button): Here are some equivalent values: Binary numbers also have a beautiful and elegant pattern: Here are some larger values: "Binary is as easy as 1, 10, 11." Now see how to use Binary to count past 1,000 on your fingers: In the Decimal System there are Ones, Tens, Hundreds, etc. In Binary there are Ones, Twos, Fours, etc, like this: Numbers can be placed to the left or right of the point, to show values greater than one and less than one.

gets 2 times bigger . gets 2 times smaller (half as big). The "10" means 2 in decimal, The ".1" means half, So "10.1" in binary is 2.5 in decimal. The word binary comes from "Bi-" meaning two. We see "bi-" in words such as "bicycle" (two wheels) or "binocular" (two eyes). A single binary digit (like "0" or "1") is called a "bit". For example 11010 is five bits long. The word bit is made up from the words " b inary dig it " How to Show that a Number is Binary. To show that a number is a binary number, follow it with a little 2 like this: 101 2. This way people won't think it is the decimal number "101" (one hundred and one). Example: What is 1111 2 in Decimal? The "1" on the left is in the "2×2×2" position, so that means 1×2×2×2 (=8) The next "1" is in the "2×2" position, so that means 1×2×2 (=4) The next "1" is in the "2" position, so that means 1×2 (=2) The last "1" is in the ones position, so that means 1 Answer: 1111 = 8+4+2+1 = 15 in Decimal. Example: What is 1001 2 in Decimal? The "1" on the left is in the "2×2×2" position, so that means 1×2×2×2 (=8) The "0" is in the "2×2" position, so that means 0×2×2 (=0) The next "0" is in the "2" position, so that means 0×2 (=0) The last "1" is in the ones position, so that means 1 Answer: 1001 = 8+0+0+1 = 9 in Decimal. Example: What is 1.1 2 in Decimal?

The "1" on the left side is in the ones position, so that means 1. The 1 on the right side is in the "halves" position, so that means 1×(12) So, 1.1 is "1 and 1 half" = 1.5 in Decimal. Example: What is 10.11 2 in Decimal? The "1" is in the "2" position, so that means 1×2 (=2) The "0" is in the ones position, so that means 0 The "1" on the right of the point is in the "halves" position, so that means 1×(12) The last "1" on the right side is in the "quarters" position, so that means 1×(14) So, 10.11 is 2+0+12+14 = 2.75 in Decimal. "There are 10 kinds of people in the world, those who understand binary numbers, and those who don't."
