complement number การใช้

• That forces the multiplication process to be adapted to handle two's complement numbers, and that complicates the process a bit more.
• It turns out that this is simply done, using an unsigned subtraction, and simply interpreting the result as a signed two's complement number.
• If the exponent were represented as, say, a 2's-complement number, comparison to see which of two numbers is greater would not be as convenient.
• A horizontal bar hides either all the complement numbers when it is slid to the top, or all the direct numbers when it is slid toward the center of the machine.
• 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.
• When turning a two's-complement number with a certain number of bits into one with more bits ( e . g ., when copying from a 1-byte variable to a 2-byte variable ), the most-significant bit must be repeated in all the extra bits.
