# Math-rs

## 简介

使用纯rust编写的表达式解析、运算库。支持常见数学运算、设置变量。

## Example

```rust

use mathrs::expr::Expression;

let mut expr = Expression::parse("1 + 2*3 - x1 * x2");

expr.set_variable("x1", "2")

    .set_variable("x2", "2 * 2");

let result = expr.excute();

println!("result = {}", result);

expr.set_variable("x1", "sin(3.14)")

    .set_variable("x2", "1");

let result = expr.excute();

println!("result = {}", result);

```
