Why is my code not working?

I do not understand why this line of code is not working? This is what is states on MDN, am I missing something?

script.js 
var temperature=37.5;
Math.floor(temperature);
alert(temperature);
index.html 
<!DOCTYPE HTML>
<html>
<head>
  <meta http-equiv="Content-Type" content="text/html; charset=UTF-8">

<script src="script.js"></script>

You need to alert the whole thing. Right now you're only alerting temperature which still holds 37.5.

So for the first challenge they want you to alert a rounded number and the second challenge they want you to round down and alert this. 

var temperature = 37.5;
// First challenge, alerting the rounded temperature
alert(Math.round(temperature));

// Second challenge, alerting the rounded down temperature
alert(Math.floor(temperature));

Hopefully this clears some things up, if not - ask again. Happy coding!
