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.
