使用说明与常见问题How-to & FAQ

「打乱整数列表顺序」是什么？What is the Shuffle Integers tool?

随机打乱整数列表的顺序（可设种子复现）。本地处理。可设置「种子（留空 = 真随机）」、「分隔」、「千位逗号」。Randomly shuffle the order of a list of integers (optional seed). Processed locally. Settings: Seed (blank = truly random), Separator, Thousands commas.

如何使用「打乱整数列表顺序」？How do I use the Shuffle Integers tool?

在「打乱整数列表顺序」中，把内容粘贴或输入到上方输入框，按需设置「种子（留空 = 真随机）」、「分隔」，结果会实时显示在下方，点击「复制结果」即可复制。Paste a list of integers and the page puts them in a random order. Leave "Seed" blank for a fresh shuffle, or enter any value to get the same order again; choose the "Separator", optionally tick "Thousands commas", and click "Copy result" to copy the list.

怎样输入多个整数？How do I enter several integers?

每行一个，或用空格、逗号、分号分隔。像 1,234,567 这样每 3 位一个逗号的写法按千位分隔读作一个数（所以 10,100 是 10100，要表示两个数请写 10 100）；也可以用下划线分组（1_000）。负号可用 -、−（U+2212）或全角 －，全角数字也能识别。小数、科学计数法（1e3）或夹杂文字会报错并指出是第几个、完整显示那个值。One per line, or separated by spaces, commas or semicolons. A value with a comma every three digits, like 1,234,567, is read as one number with thousands separators (so 10,100 is 10100; write 10 100 for two values); underscores also group digits (1_000). Minus can be a hyphen, the Unicode minus (U+2212) or the fullwidth minus, and fullwidth digits work. Decimals, scientific notation (1e3) or stray text give an error naming the position and showing the whole value.

结果精确吗？Are the results exact?

精确。所有整数都按大整数（BigInt）逐位处理，不经过浮点，超过 2^53 的数（例如 9007199254740993）也不会被舍入。粘贴几千上万行也是线性处理，通常在几十毫秒内完成。Yes. Every value is handled as a big integer (BigInt) with no floating-point step, so numbers above 2^53 such as 9007199254740993 are never rounded. Pasting thousands of lines is processed in linear time, usually within tens of milliseconds.

输入和输出是什么样的？What does the input and output look like?

例如在「打乱整数列表顺序」中输入 1 ⏎ 2 ⏎ 3，「种子（留空 = 真随机）」设为 1，输出为：1 ⏎ 3 ⏎ 2（⏎ 表示换行）。For example, the Shuffle Integers turns the input 1 ⏎ 2 ⏎ 3, "Seed (blank = truly random)" set to 1 into: 1 ⏎ 3 ⏎ 2 (⏎ marks a line break).

有哪些选项可以调整？What options can I adjust?

「打乱整数列表顺序」的设置：「种子（留空 = 真随机）」可留空；「分隔」可选 每行一个、空格、逗号、分号（默认 每行一个）；可勾选：「千位逗号」。改动任一选项后结果会按新设置重新生成。Settings in the Shuffle Integers — "Seed (blank = truly random)" optional; "Separator": One per line, Spaces, Commas, Semicolons (default One per line); tick boxes: "Thousands commas". Changing any option regenerates the result with the new setting.
