Math.floor

I don't understand why this one is not working.

var temperature = 37.5; alert(Math.floor(temperature));

script.js 
var temperature = 37.5;

alert(Math.floor(temperature));

Your are supposed to round the number, not floor.

You shouldn't remove the previous task's code :)

I did that on the first challenge and for that one the challenge is this: 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".)
