Calculator Tool

The CalculatorTool evaluates mathematical expressions using the meval crate. It supports arithmetic, power, trigonometric, and logarithmic functions — perfect for agents that need to perform calculations without hallucinating.

Setup

[dependencies]
synaptic = { version = "0.4", features = ["tools"] }

No API key required.

Usage

use synaptic::tools::CalculatorTool;
use synaptic::core::Tool;
use serde_json::json;

let tool = CalculatorTool;

let result = tool.call(json!({"expression": "2 + 3 * 4"})).await?;
// {"expression": "2 + 3 * 4", "result": 14.0}

let result = tool.call(json!({"expression": "sqrt(144) + log(10)"})).await?;

Supported Operations

Notes

• The calculator uses the meval crate for expression parsing.
• Division by zero and other undefined operations return an error.
• All results are returned as 64-bit floating-point values.
