質問: 計算機概論的題目 只要答案就可以了 1.把10進數255.625轉成2進數=? 2.把中序式-a+x^b+y/c-d*e轉成前序式 3.a microarchitecture is one specific implementation of an instruction set architecture 此敘述是否為正確,如果錯誤的話請解釋原因
回答: 1. 255.625 = 255 + .5 + .125 = ff16 + .5 + .125 = 11111111.1012 2. - / \ + * / \ / \ + ÷ d e / \ / \ - ^ y c / / \ a x b -++-a^xb÷yc*de 沒細查(應該沒錯就是了。),你再對一下。 3. it is wrong if you are picky. the word, microarchitecture, refers to the method instead of the result. the sentence in this question is talking about the result. 2011-02-24 10:37:17 補充: 1. 的 0.625 有另一解法,也很快! 0.625 = 5/8 = 101 / 111 = 0.101(2) 2011-02-24 10:38:09 補充: 分母寫111 是錯的!就是它是8進位的東東就是了!
