|This enables a number of optimizations, but also leads to a number of strange bugs in such undefined programs||There are a special case also|
|The , introduced in 1964 by , then the dominant player in the computer industry, made two's complement the most widely used binary representation in the computer industry||C Assignment Operators An assignment operator is used for assigning a value to a variable|
As to get a number in its binary form, we have to divide it by 2, until it gets 0, which will take log 2N of time.
|Even though the unnecessary steps have been eliminated, it's extremely inefficient||There isn't usually a problem when the multiplicand the one being repeatedly added to form the product is negative; the issue is setting the initial bits of the product correctly when the multiplier is negative|
|That means that the generator polynomials will be 9, 17, or 33 bits wide, respectively||Therefore, the most positive 4 bit number is 0111 7|
Similarly, when a two's-complement number is shifted to the right, the most-significant bit, which contains magnitude and the sign information, must be maintained.21
