If we have three binary bits, then we can represent eight numbers, starting from 0 to 7. So, in other words, 0 to 7 is the range of numbers that we can represent using three binary bits. However, this range is defined for unsigned magnitude numbers. In this article, we will get to know the…
In an earlier article, we learned about 2’s complement addition. In this article, we will discuss how to perform 1’s complement addition. We will consider the same example that is taken for the 2’s complement addition. Important Rule: Add the two numbers using the basic rules of binary addition. If there is a carry out…

Many a time, overflow in a binary addition seems like a final carry generation. However, overflow leads to an incorrect sum, whereas carry does not. This is a little confusing if not understood correctly. So, let’s understand the overflow concept clearly. Imagine you have a half-tea-filled cup. Your friend has a jar with some amount…
Addition and subtraction of 2’s complement signed binary numbers are important learning concepts, as digital computers use 2’s complement representation. 2’s complement arithmetic follows all the basic rules of binary arithmetic. However, a few tricks need to be learned so that we can get the correct result in its 2’s complement form. This article discusses…

All of you must have heard about the chip shortage in the recent news. The global chip shortage 2020-2021 is an ongoing crisis that affected multiple sectors. What do you understand from global chip shortage, then? Chip shortage, alternatively known as semiconductor shortage, arises when the demand for semiconductor chips becomes higher than the supply….
Binary arithmetic is essential in all digital computers and in many other types of digital systems. Now, since we know about different number systems and signed numbers, this is the right time to learn about binary arithmetic and the associated rules. First, we would learn about the basic rules of binary arithmetic, and solve some…
Using unsigned magnitude form, we can only represent the positive numbers. Whereas, using signed magnitude form, we can represent both positive as well as negative numbers. In this article, we will highlight a few differences between the signed and unsigned magnitude forms of representing binary numbers. Unsigned Magnitude Signed Magnitude What can be represented…

Now that we have learned about signed number binary representation, let’s discuss how to find out the decimal value of a signed binary number if the format of the representation is known. Sign-Magnitude Form: Example: An 8-bit binary number represented in sign-magnitude form is 10010101. Find the decimal value of the number. Answer: The given…

Positive integers, including zero, can be represented as unsigned numbers. However, digital systems, such as the computer, must be able to handle both positive and negative numbers. To represent negative integers, we need a notation for negative values. In ordinary arithmetic, a negative number is indicated by a minus sign and a positive number by…
In a recent article, we have seen how to convert a binary number to its corresponding octal as well as hexadecimal number. However, in that article, we have considered the conversions for only the whole numbers. In this article, we will do the conversions for the binary fractional numbers. Following is the technique for such…
