Chapter 3 Number Systems and Boolean Algebra 3.1.2 Positional notation n the decimal system, positions to the right of the decimal point have negative powers. The first digit to the right of the decimal point has a value of 10-1, or 0.1. In the binary system, the first digit to the right of the binary point has a value of 2-1. or 0.5. In general, the principles that apply to decimal numbers also apply to numbers in any other number system. 在十进制系统中,对于十进制小数点右边的位,它的幂为负 数。十进制小数点右边第一位数的值为10-1,或0.1。在二进 制中,二进制小数点右边第一位数的值为2-或05。一般来说, 十进制使用的计数法可以用于任何其他数制。 《什第机专出美语 31Chapter 3 Number Systems and Boolean Algebra 计算机专业英语 3-11 In the decimal system, positions to the right of the decimal point have negative powers.
