就像数学一样,用+-符号来表示正负数,对于计算机一种明显的实现方式是增加一个符号位,此时整个数字被分成两部分组成:符号(sign)和大小(magnitude),这种方式虽然最明显直接,但是存在三个缺点: 首先,符号位放在什么位置,最高位或者最低位? 其次,对于用sign 和 magnitude表示的数字,进行加法运算时,需要额外的步骤来设置...

Since the significands for addition/subtraction are expressed in a signed-magnitude number representation, the swapping operation of the two operands is required. Moreover, the carry propagation in the addition will also limit the arithmetic speed. In this paper, we introduce a radix-two signed-...
