使用说明与常见问题How-to & FAQ
「10 的幂」是什么？What is the Power of 10 Calculator tool?
计算 10ⁿ，也可由 y 求 n = log₁₀(y)。可设置「模式」、「数值」。Compute 10ⁿ, or n = log₁₀(y). Settings: Mode, Value.
如何使用「10 的幂」？How do I use the Power of 10 Calculator tool?
在「模式」中选择计算 10ⁿ 还是求 n = log₁₀(y)，再填写数值即可。结果会随输入实时更新。Choose under Mode whether to compute 10ⁿ or n = log₁₀(y), then enter the value. The result updates as you type.
注意Note
极大指数可能溢出为 Infinity。Huge exponents may overflow to Infinity.
能举个计算实例吗？Can you show a worked example?
例如在「10 的幂」中填 模式 = 10ⁿ，数值 = 3，结果区显示：10ⁿ：1,000For example, entering Mode = 10ⁿ, Value = 3 in the Power of 10 Calculator gives: 10ⁿ: 1,000
哪些输入会被检查？Which inputs are validated?
「10 的幂」会检查这些输入——「数值」：必须填写，须大于 0；绝对值超过 10¹⁵ 的数也会被拒绝。不符合时结果区显示具体提示，不会给出数字。The Power of 10 Calculator checks its inputs — "Value": required, must be greater than 0; numbers above 10¹⁵ in absolute value are rejected too. When a value fails, the result area names the problem instead of showing a number.
有哪些选项可以调整？What options can I adjust?
「10 的幂」的设置：「模式」可选 10ⁿ、log₁₀(y)（默认 10ⁿ）；「数值」默认 3。每次生成结果都按当前设置处理。Settings in the Power of 10 Calculator — "Mode": 10ⁿ, log₁₀(y) (default 10ⁿ); "Value" default 3. The result always uses the current settings.
计算精度如何？How precise are the results?
「10 的幂」使用 JavaScript 双精度浮点数（约 15–16 位有效数字）；极大或极小的数值可能存在精度误差。The Power of 10 Calculator uses double-precision floating point (about 15–16 significant digits); very large or very small values may lose precision.
「10 的幂」免费吗？需要注册吗？Is the Power of 10 Calculator free? Do I need an account?
「10 的幂」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 Power of 10 Calculator is completely free with no sign-up or install and works on phones and desktops; what you enter is processed only in your browser.
