Chapter 4 in page 5有提到:
Start from 0 and continuously add 1 until you get to 127; If you add one more, you do
not get 128;you get –128;Add one more and you get –127. Add one more and you
get –126. This is what happened in Example 4.
0111 1111=127对吧?
+ 0000 0001
__________________________
1000 0000=-128还是等於0?
再加1变成
1000 0001=-127?
是这样的吗?...
不太懂
