本頁主要討論swift語言裡的整形資料和浮點數。

1 int整形，有符號整形資料，是和電腦平台cpu位元組數相關的資料類型。

   即，在8位電腦的int型整形，佔一位元組int；在16位電腦上int代表2字

   節整形資料，因此平時我們熟知的32位電腦的int型資料佔四位元組，可

   以表示的數 min:-2147483648  max:2147483647（-2^31 ~ 2 ^31 - 1）

2 uint，無符號整形資料，只有0和正整數（0~ 2 ^32 - 1）

3 swift有預定義UInt類型和UInt64無符號整形類型

4 浮點數有32位的Float型浮點數和64位的Double浮點數

英語讀書筆記70詞 My life in the University 各位

My University Life
University, a good name, a beautiful place. Many students dream of it. After college entrance examination, I chose XXX University. I believed my dream would become true there.

Fortunately, I was accepted by XXX University. Now, I’m standing outside my dormitory on the fourth floor, locking the green campus, thinking, thinking……

On thinking I’ll spend my four-year university life here. I feel not only excited but also nervous and challenging.

Indeed, in such short time, I feel free as if I was a bird which just flied out of a cage. There are fewer lessons, and also I don’t have to get up earlier. In a word, there is enough time for me to study alone, to visit the library, to wander……

In addition, I feel the pressure of the competition here. There are so many persons of ability. Several days ago, I failed. But as we all know, nothing is too unsuccessful if you put your heart into trying it. It’s just a beginning. I believe there will be more chances to temper and present myself.

In short, I hope my university life is full of happiness, rather than sadness.

At last, I want to say, dream is sowed here and also success will be harvested here.
