Usage

Here's a basic example of how to use SimpleCalc:

fn main() {
    match simplecalc::eval("1+2-3*4/5**6") {
        Ok(res) => println!("{res}"),
        Err(e) => println!("{e}"),
    }
}

Evaluate an expression:

let result = simplecalc::eval("10 + 5 * 2")?;
println!("{}", result); // Outputs: 20

Handle invalid expressions:

println!("{}", simplecalc::eval("invalud expression").err().unwrap());
