使用说明与常见问题How-to & FAQ
「生成奇数」是什么？What is the Generate Odd Numbers tool?
生成一段奇数：可设个数、起点与步长（默认 2）。本地处理。可设置「个数」、「起点」、「步长」。Generate odd numbers: set how many, start, and step (default 2). Processed locally. Settings: How many, Start, Step.
如何使用「生成奇数」？How do I use the Generate Odd Numbers tool?
在「生成奇数」中，按需设置「个数」、「起点」、「步长」，结果会实时显示在下方，点击「复制结果」即可复制。In the Generate Odd Numbers: Adjust "How many", "Start", "Step"; the result appears below instantly — click "Copy result" to copy it.
起点是偶数会怎样？What if Start is even?
自动调到邻近的奇数（正数加 1，负数减 1）再按步长递增。It moves to the neighbouring odd number (up by 1 for positive values, down by 1 for negative ones), then steps from there.
数值范围是多少？结果精确吗？What are the limits? Are the results exact?
「个数」1–20000；「起点」可以是任意整数（最多 1000 位，例如 100000000000000000001），按大整数（BigInt）计算，不经过浮点，所以每个结果都是精确的奇数；小数或 1e20 这类写法会提示须为整数。「步长」须为非 0 的偶数，绝对值最多 10^9。留空的框按默认值计算：「个数」20、「起点」1、「步长」2。How many: 1–20,000. Start can be any whole number up to 1,000 digits (for example 100000000000000000001); it is computed with big integers (BigInt), with no floating-point step, so every result is an exact odd number. Decimals or forms like 1e20 give a "must be an integer" message. Step must be a non-zero even number with absolute value up to 10^9. An empty box uses its default: How many 20, Start 1, Step 2.
输入和输出是什么样的？What does the input and output look like?
例如在「生成奇数」中把「个数」设为 4，「起点」设为 1，输出为：1 ⏎ 3 ⏎ 5 ⏎ 7（⏎ 表示换行）。For example, in the Generate Odd Numbers with "How many" set to 4, "Start" set to 1, the output is: 1 ⏎ 3 ⏎ 5 ⏎ 7 (⏎ marks a line break).
有哪些选项可以调整？What options can I adjust?
「生成奇数」的设置：「个数」默认 20；「起点」默认 1；「步长」默认 2。每次生成结果都按当前设置处理。Settings in the Generate Odd Numbers — "How many" default 20; "Start" default 1; "Step" default 2. The result always uses the current settings.
