Math & Numbers
通过分步反馈练习有效数字规则：数有效数字、四舍五入到 N 位、转科学计数法、以及在 +/−/×/÷ 运算中传递有效数字。
用三种语言从你的代码中调用此工具。
curl -X POST 'https://api.elysiatools.com/zh/api/tools/significant-figures-sandbox' \
-H 'Content-Type: application/json' \
-d '{"number":"0.005030","mode":"practice","guess":4,"roundN":0,"sciDigits":0,"opA":"e.g. 12.5","opB":"e.g. 3.20","operation":"+"}'以 JSON 形式 POST 提交输入参数。文件类型参数需先单独上传。
POST https://api.elysiatools.com/zh/api/tools/significant-figures-sandbox| 参数名 | 类型 | 必填 | 说明 |
|---|---|---|---|
| number | text | 是 | The number to analyse. Accepts integers, decimals, leading zeros, and scientific notation (1.23e4, 1.23E4, 1.23×10^4). |
| mode | select | 否 | Practice gives feedback on your sig-fig guess. Round rounds to N sig figs. Propagate applies the +/−/×/÷ rule to two operands. |
| guess | number | 否 | Practice mode only: enter your guess to get correct/incorrect feedback. |
| roundN | number | 否 | Round mode only: how many sig figs to round to. Defaults to the number's own count. |
| sciDigits | number |
将此工具加入你的 Model Context Protocol 服务，让 AI 智能体可以列出并调用它。
将以下内容加入你的 MCP 客户端配置：
