signandmagnitude notation 符号数值表示法 A computer convention in which the left most bit in a data word is interpreted as a sign bit (0 is positive, 1 negative) and the remaining bits represent the magnitude, with the MSB just to the right of the sign bit. Usually the binary point is agreed to be between the sign bit and the MSB, making the quantity a fraction. 一种计算机的约定,数据字中最左边的位解释成符号位(0为正,1为负),其余各位表示数值, 其最大有效位(MSB)在符号位的右边。通常将二进制小数点放在符号位和最大有效位(MSB) 之间,使整个量成为一个小数。 |
