5Fdostey:有趣!問題是0.99..終究還是沒辦法走到1,只能在條件下達成05/08 02:03
7Fdostey:樓上幹嘛噓噓呢:05/08 02:04
11Fdostey:所以元po指的是在Sn趨近1時(條件下), 0.9 = 1?05/08 02:10
12Fdostey: 0.99..=105/08 02:11
24Fdostey:循環小數的定義用"趨近"(在Sn趨近1時),是否可說不是真等於05/08 02:13
28Fdostey:e14e8d你是只在無窮時(沒辦法明確指出數位個數),所以05/08 02:16
29Fdostey:0.9+0.09+0.009+...=1?05/08 02:16
33Fdostey:以上看來,0.99...=1 確實是成立的,在人為定義下!05/08 02:19
39Fdostey:看來112筆我們哪年代的112還強歐!元po該不會是哲學系的吧?05/08 02:25
45Fdostey:哎呀el4e8d,你是再找我嗎?05/08 02:29
