「生成平方数列」是什么？What is the Generate Sequence of Squares tool?

生成 n² 数列：1², 2², … 或指定起点。本地处理。可设置「个数」、「起点 n」。Generate squares n²: 1², 2², … or from a chosen start. Processed locally. Settings: How many, Start n.

如何使用「生成平方数列」？How do I use the Generate Sequence of Squares tool?

在「生成平方数列」中，按需设置「个数」、「起点 n」，结果会实时显示在下方，点击「复制结果」即可复制。In the Generate Sequence of Squares: Adjust "How many", "Start n"; the result appears below instantly — click "Copy result" to copy it.

和立方数列有什么不同？How does it differ from the cubes sequence?

界面和用法一样，只是指数不同：本页算 n²，立方数列算 n³。负数的平方是正数，所以起点为 −3 时会得到 9、4、1、0、1……Same interface and usage; only the power differs: this page gives n² and the cubes page n³. Squares of negatives are positive, so starting at −3 gives 9, 4, 1, 0, 1, …

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

例如在「生成平方数列」中把「个数」设为 5，「起点 n」设为 1，输出为：1 ⏎ 4 ⏎ 9 ⏎ 16 ⏎ 25（⏎ 表示换行）。For example, in the Generate Sequence of Squares with "How many" set to 5, "Start n" set to 1, the output is: 1 ⏎ 4 ⏎ 9 ⏎ 16 ⏎ 25 (⏎ marks a line break).

有哪些选项可以调整？What options can I adjust?

「生成平方数列」的设置：「个数」默认 10；「起点 n」默认 1。每次生成结果都按当前设置处理。Settings in the Generate Sequence of Squares — "How many" default 10; "Start n" default 1. The result always uses the current settings.

计算精度如何？How precise are the results?

「生成平方数列」中的整数都用大整数（BigInt）精确计算，不经过浮点，所以再长的项也不会丢失位数；输入超出页面说明的范围时会给出提示，而不是悄悄截断。Integers in the Generate Sequence of Squares are computed exactly with big integers (BigInt), with no floating-point step, so even very long terms keep every digit; values outside the stated ranges give a message instead of being silently cut off.

「生成平方数列」免费吗？需要注册吗？Is the Generate Sequence of Squares free? Do I need an account?
