how do i get Math.floor() yo work so i can mark down the temperature?

Open an alert dialog a second time and display the temperature variable rounded downward to the nearest integer. You'll need to check the Mozilla Developer Network to find the proper Math method for this (hint: down is toward the "floor".)

script.js 
var temperature = Math.around(37.5);
alert('temperature');
index.html

First, we won't need to do anything in the index.html page, so let's ignore that and only focus on script.js.

We are asked to open an alert dialog that displays the variable rounded downward to the nearest integer, so we'll use the floor method.

Since temperature already has a value, we can call the floor method within the alert dialog box like so:

var temperature = 37.5;

alert(Math.round(temperature));
alert(Math.floor(temperature));
