# `Math` [View this example online](https://webassembly.studio/?f=ffnm4kpzmib) This directory is an example of using the `#[wasm_bindgen]` macro to import the `Math` object and invoke various functions on it. You can build the example with: ``` $ ./build.sh ``` (or running the commands on Windows manually) and then opening up `index.html` in a web browser should show a dialog! For more information about this example be sure to check out [`hello_world`][hello] which also has more comments about caveats and such.
