第一周作业参考答案 3.11011.011(B)=27.375(D)=33.3(O)=1B.6(H) 4.240.75(D)=110000.11(B)=360.6(O)=0.C(H) 5 E3(H)=11100011() E3(H)为原码时,x=-110011(B)=-99(D) E3(H)为反码时,[]原=10011100(B)(x=-11100=-28(D) E3(H)为补码时,[]原=10011101(B),(x=-11101=-29(D) E3(H)为无符号数时,X=E3(H)=227(D) 因为E3(H)的高4位E(H)=14(D)超出了0~9的范围,所以E3(H)不可能为压缩BCD码
