使用说明与常见问题How-to & FAQ
「二进制减法计算器」是什么？What is the Binary Subtraction Calculator tool?
两个非负二进制整数相减，要求被减数 ≥ 减数，结果非负。给出二进制差与十进制。本地处理。Subtract non-negative binaries with minuend ≥ subtrahend (non-negative result). Shows binary difference and decimal. Processed locally.
如何使用「二进制减法计算器」？How do I use the Binary Subtraction Calculator tool?
在「二进制减法计算器」中，填写「被减数」、「减数」等参数，结果会随输入实时计算并显示在下方。In the Binary Subtraction Calculator: Fill in "Minuend", "Subtrahend"; results are recalculated instantly as you type.
结果可以是负数吗？Can the result be negative?
不可以，本页要求被减数不小于减数（A ≥ B），结果非负。如果 B 更大，可以交换两数相减后加负号，或用二进制补码表示负数。No, the minuend must be at least the subtrahend (A ≥ B), so the result is not negative. If B is larger, swap them and add a minus sign, or use two's complement for negative values.
能举个计算实例吗？Can you show a worked example?
例如在「二进制减法计算器」中填 被减数 = 1011，减数 = 110，结果区显示：差（二进制）：101；十进制：5For example, entering Minuend = 1011, Subtrahend = 110 in the Binary Subtraction Calculator gives: Difference (binary): 101; Decimal: 5
有哪些选项可以调整？What options can I adjust?
「二进制减法计算器」的设置：「被减数」默认 1011；「减数」默认 110。每次生成结果都按当前设置处理。Settings in the Binary Subtraction Calculator — "Minuend" default 1011; "Subtrahend" default 110. The result always uses the current settings.
计算精度如何？How precise are the results?
「二进制减法计算器」使用 JavaScript 双精度浮点数（约 15–16 位有效数字），部分功能使用 BigInt 处理大整数。The Binary Subtraction Calculator uses double-precision floating point (about 15–16 significant digits); some features use BigInt for large integers.
「二进制减法计算器」免费吗？需要注册吗？Is the Binary Subtraction Calculator free? Do I need an account?
「二进制减法计算器」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 Binary Subtraction 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.
