Basic Pascal Tutorial/Chapter 2/Formatting output/zh CN: what changed
Revision 1 to 2. Removed lines have a minus sign; added lines have a plus sign.
| Old | New | Line | |
|---|---|---|---|
| 1 | 1 | 2C - 格式化输出 (原作者: Tao Yue, 状态: 未更改) | |
| 2 | 2 | ||
| 3 | 3 | 格式化输出很易用，如下： | |
| 4 | 4 | ||
| 5 | 5 | ``` pascal | |
| 6 | 6 | 值 : 字段长度 | |
| 7 | 7 | ``` | |
| 8 | 8 | ||
| 9 | 9 | 字段长度指，显示的数据右对齐后占用的宽度。如果宽度不足以显示全部数据，那么指定的字段长度将被忽略（看下面示例）。 | |
| 10 | 10 | ||
| 11 | 11 | 如下语句： | |
| 12 | 12 | ||
| 13 | 13 | ``` pascal | |
| 14 | 14 | write ('Hi':10, 5:4, 5673:2); | |
| 15 | 15 | ``` | |
| 16 | 16 | ||
| 17 | 17 | 输出将是（Hi前面有8个空格，后面有3个。） | |
| 18 | 18 | ||
| 19 | - | ||
| 19 | + | ``` | |
| 20 | + | Hi 55673 | |
| 21 | + | ``` | |
| 20 | 22 | ||
| 21 | 23 | 你可以设置字段长度，以科学计数法形式显示实数。也可以指定小数位数： | |
| 22 | 24 | ||
| 23 | 25 | ``` pascal | |
| 24 | 26 | 值 : 字段长度 : 小数位 | |
| 25 | 27 | ``` | |
| 26 | 28 | ||
| 27 | 29 | 字段长度是总占用宽度，包括小数部分。如果宽度无法显示全部数值，整数部分将会被显示出来；如果小数位超出设定的位数，将被四舍五入。 | |
| 28 | 30 | ||
| 29 | 31 | ``` pascal | |
| 30 | 32 | write (573549.56792:20:2); | |
| 31 | 33 | ``` | |
| 32 | 34 | ||
| 33 | 35 | 会是什么样子（有11个空格在前面）？ | |
| 34 | 36 | ||
| 35 | - | ||
| 37 | + | ``` | |
| 38 | + | 573549.57 | |
| 39 | + | ``` | |
| 36 | 40 | ||
