Math & Numbers

有效数字沙盒

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。

快速开始

用三种语言从你的代码中调用此工具。

cURL
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":"+"}'

API 参考

以 JSON 形式 POST 提交输入参数。文件类型参数需先单独上传。

请求端点

HTTP
POST https://api.elysiatools.com/zh/api/tools/significant-figures-sandbox

请求参数

参数名类型必填说明
numbertext是The number to analyse. Accepts integers, decimals, leading zeros, and scientific notation (1.23e4, 1.23E4, 1.23×10^4).
modeselect否Practice gives feedback on your sig-fig guess. Round rounds to N sig figs. Propagate applies the +/−/×/÷ rule to two operands.
guessnumber否Practice mode only: enter your guess to get correct/incorrect feedback.
roundNnumber否Round mode only: how many sig figs to round to. Defaults to the number's own count.
sciDigitsnumber

MCP 集成

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。

服务配置

将以下内容加入你的 MCP 客户端配置:

mcp.json
{
  "mcpServers": {
    "elysiatools-significant-figures-sandbox": {
      "name": "significant-figures-sandbox",
      "description": "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。",
      "baseUrl": "https://api.elysiatools.com/mcp/sse?toolId=significant-figures-sandbox",
      "command": "",
      "args": [],
      "env": {},
      "isActive": true,
      "type": "sse"
    }
  }
}

列出可用工具

连接到 SSE 端点后,列出已开放的工具:

tools/list
{
  "jsonrpc": "2.0",
  "id": 1,
  "method": "tools/list"
}

调用此工具

通过工具 id 调用,参数由其参数表构建:

tools/call
{
  "jsonrpc": "2.0",
  "id": 2,
  "method": "tools/call",
  "params": {
    "name": "significant-figures-sandbox",
    "arguments": {
  "number": "0.005030",
  "mode": "practice",
  "guess": 4,
  "roundN": 0,
  "sciDigits": 0,
  "opA": "e.g. 12.5",
  "opB": "e.g. 3.20",
  "operation": "+"
}
  }
}
可用逗号分隔的 toolId 在一个会话中串联多个工具,例如 /mcp/sse?toolId=png-to-webp,jpg-to-webp,gif-to-webp(最多 20 个)。
