使用说明与常见问题How-to & FAQ
「生成亏数」是什么?What is the Generate Deficient Numbers tool?
生成真因数之和小于自身的亏数。可设个数与起点,本地处理。可设置「个数」、「起点」。Generate deficient numbers (proper-divisor sum less than the number). Set how many and where to start. Processed locally. Settings: How many, Start.
如何使用「生成亏数」?How do I use the Generate Deficient Numbers tool?
在「生成亏数」中,按需设置「个数」、「起点」,结果会实时显示在下方,点击「复制结果」即可复制。In the Generate Deficient Numbers: Adjust "How many", "Start"; the result appears below instantly — click "Copy result" to copy it.
质数是亏数吗?Are primes deficient?
是。质数的真因数只有 1,和为 1 < p。Yes. A prime's only proper divisor is 1, so the sum is 1 < p.
输入和输出是什么样的?What does the input and output look like?
例如在「生成亏数」中把「个数」设为 5,「起点」设为 1,输出为:1 ⏎ 2 ⏎ 3 ⏎ 4 ⏎ 5(⏎ 表示换行)。For example, in the Generate Deficient Numbers with "How many" set to 5, "Start" set to 1, the output is: 1 ⏎ 2 ⏎ 3 ⏎ 4 ⏎ 5 (⏎ marks a line break).
有哪些选项可以调整?What options can I adjust?
「生成亏数」的设置:「个数」默认 20;「起点」默认 1。每次生成结果都按当前设置处理。Settings in the Generate Deficient Numbers — "How many" default 20; "Start" default 1. The result always uses the current settings.
计算精度如何?How precise are the results?
「生成亏数」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 Deficient Numbers 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.
「生成亏数」免费吗?需要注册吗?Is the Generate Deficient Numbers free? Do I need an account?
「生成亏数」完全免费,无需注册或安装,打开网页即可使用,手机和电脑都能用;输入的内容只在你的浏览器本地处理。The Generate Deficient Numbers is completely free with no sign-up or install and works on phones and desktops; what you enter is processed only in your browser.
