🎲 打乱整数各位数字Shuffle Integer Digits

使用说明与常见问题How-to & FAQ

「打乱整数各位数字」是什么？What is the Shuffle Integer Digits tool?

随机打乱每个整数的各位数字（可设种子），保留符号。本地处理。可设置「种子（留空 = 真随机）」、「去掉前导零」。Randomly shuffle the digits of each integer (optional seed), keeping the sign. Processed locally. Settings: Seed (blank = truly random), Drop leading zeros.

如何使用「打乱整数各位数字」？How do I use the Shuffle Integer Digits tool?

在「打乱整数各位数字」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）」，结果会实时显示在下方，点击「复制结果」即可复制。Paste integers and each one gets its digits shuffled, keeping the sign. Leave "Seed" blank for a fresh random order, or enter any value to repeat it; tick "Drop leading zeros" to tidy results such as 012, then click "Copy result" to copy them.

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.

会保留前导零吗？Are leading zeros kept?

默认保留：打乱后每一位都还在，所以 1000 可能得到 0100。勾选「去掉前导零」后输出 100 这样的整数写法。负号保持在最前面。By default yes: every digit is kept, so 1000 may become 0100. Tick Drop leading zeros to get integer form such as 100. A minus sign stays in front.

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

例如在「打乱整数各位数字」中输入 1234，「种子（留空 = 真随机）」设为 1，输出为：1342（⏎ 表示换行）。For example, the Shuffle Integer Digits turns the input 1234, "Seed (blank = truly random)" set to 1 into: 1342 (⏎ marks a line break).

有哪些选项可以调整？What options can I adjust?

「打乱整数各位数字」的设置：「种子（留空 = 真随机）」可留空；可勾选：「去掉前导零」。改动任一选项后结果会按新设置重新生成。Settings in the Shuffle Integer Digits — "Seed (blank = truly random)" optional; tick boxes: "Drop leading zeros". Changing any option regenerates the result with the new setting.

「打乱整数各位数字」免费吗？需要注册吗？Is the Shuffle Integer Digits free? Do I need an account?
