A binary - coded decimal code for representing decimal numbers in which each decimal digit is represented by seven binary digits which are coefficients of8 , 6 , 4 , 2 , 0 , 1 , 0 , respectively 用于表示十进制数的一种二进制编码的十进制码,其中每位十进制数用七位二进制数来表示,它们分别是8 , 6 , 4 , 2 , 0 , 1和0的系数。五二码表如下:
An operation performed in boolean algebra on two binary digits simultaneously in a way that the result is one if either one or both digits are a one , or zero if both digits are zero . the logic operator is the or operator 布尔代数中的一种运算,它同时对两个二进制数字进行如下操作:如果一个数或二个数为1 ,则结果为1 ;如果二个数均为零,则结果为零。它的逻辑算符是or运算符。
