What does the cow sound like? It's moo~ moo moo ```
Mathematics interpreter utility, written without dependencies, capable of - Interpreting normal mathematics equation - Interpreting first order differential equation with Runge-Kutta method - Can add custom math function

// add custom function
functions.insert("relu", Function::new("relu", |v| {
f64::max(0.0, v)

});

// run(x) output: 10
