海外TECH	DEV Community	Representing Negative Numbers in Binary Notation	https://dev.to/andrewgl22/representing-negative-numbers-in-binary-notation-2n4m	Representing Negative Numbers in Binary NotationWe ve seen how to add two positive integers together in binary notation But what happens when we try to subtract You ll see pretty quickly that we can t subtract from in any given column so we need a different way to handle subtraction operations in binary notation There are technically different ways that negative numbers can be represented in binary The most common is called Two s Complement But before we get to it there are two other methods we need to know about Signed MagnitudeIn Base we can represent whether a number is positive or negative by adding the corresponding sign to the left of the number as in and But we don t have a way to represent the sign directly in binary we only have bits to work with Signed means adding the sign or to the number and Magnitude is a term which refers to the actual value of the number So in the number is the sign and is the magnitude of the number Binary numbers can be signed or unsigned In a signed number the left most bit is reserved to represent a positive or negative sign A in this column represents a positive sign and a represents the negative sign In unsigned the left most bit simply represents the number in that column Unsigned numbers can only represent positive numbers and zero Signed magnitude allows us to represent negative numbers in binary so this is what we will use for the rest of this post signed unsigned MSB and LSBWe have seen how the left most bit of a binary number can be reserved to represent a positive or negative sign There is actual terminology that describes this position Most Significant Bit or MSB for short describes the left most bit in a binary number This is useful for describing the signed bit of a signed binary number The Least Significant Bit or LSB describes the right most bit in a number the ones position You will come across these terms frequently as you work more with binary numbers One s ComplementWe may be able to represent a sign but we still aren t able to do an actual subtraction operation To do this in binary we need to change our thinking a bit Instead of subtracting a number we will add a negative number to the positive In binary this requires some conversion of the subtrahend number being subtracted to make it work One s complement simply means to take all the bits of a number and flip them If the bit was make it a If it was make it a one s complement of Now we can use this one s complement as the value we will add to our initial number Let s say we want to subtract from We know that one s complement of in binary is So we will add this to the binary representation of which is one s complement of You can see we are one short of the correct answer which is and our result is currently negative In One s complement computations if there is a carry bit in the MSB we do a carry around by taking the MSB and adding it to the LSB This will give us the correct answer which is It s important to note that the one s complement of a number is NOT the negative of that number For instance the one s complement of is which in binary actually represents the number The complement is just that a complementary value that when added to our minuend number to be subtracted from has the affect of giving us the correct result of a subtraction operation One s complement is a method for subtraction which is rarely used in actual computers these days it is generally used in older systems It has a shortcoming which is that it has two different representations for zero positive and negative zero zero zero One s Complement of zero Instead it is most common to see Two s ComplementTwo s Complement is just One s Complement plus one The only difference is instead of adding after the computation in Two s Complement we add to our complement before we compute the sum This is the most common form that a complement will take in binary systems Let s subtract from in binary First we must convert the number to be subtracted into it s Two s Complement in binary One s Complement of Two s Complement of First we take the One s Complement of by flipping each bit in the number then we add to the LSB to get our Two s Complement Now we are ready for our subtraction operation Since we add the one before the operation the result is the correct number In Two s Complement if our calculation has a carry in the MSB we can truncate it Our final result is ConclusionWe ve seen how to use Two s Complement to run subtraction operations on two binary numbers In the next post we will learn about Bitwise Operators which are a set of operations which gives us a lot more flexibility and greater manipulation of binary numbers	2023-03-10 21:08:26
