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 用于表示十進(jìn)制數(shù)的一種二進(jìn)制編碼的十進(jìn)制碼,其中每位十進(jìn)制數(shù)用七位二進(jìn)制數(shù)來表示,它們分別是8 , 6 , 4 , 2 , 0 , 1和0的系數(shù)。五二碼表如下:
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 布爾代數(shù)中的一種運(yùn)算,它同時(shí)對兩個(gè)二進(jìn)制數(shù)字進(jìn)行如下操作:如果一個(gè)數(shù)或二個(gè)數(shù)為1 ,則結(jié)果為1 ;如果二個(gè)數(shù)均為零,則結(jié)果為零。它的邏輯算符是or運(yùn)算符。
