MathEngine

A Rust mathematical expression evaluator with unit conversion support.

Features

• Mathematical expressions: 2 + 3 * (100.50 - 4)
• Unit conversions: 10m to feet, 23C to F
• Mixed operations: 1m to cm + 10
• Power operations: 2^10

Examples

use mathengine::{lexer::Lexer, Parser, evaluate};

let expression = "23C to F";
let lexer = Lexer::new(expression);
let tokens = lexer.tokenize();
let mut parser = Parser::new(tokens);
let ast = parser.parse().unwrap();
let result = evaluate(&ast);
println!("{}", result); // 73.4F

Supported Units

• Length: meters, centimeters, feet, inches, yards, miles
• Temperature: Celsius, Fahrenheit, Kelvin
