JavaScript JavaScript Basics (Retired) Working With Numbers Using Math Methods

Why is my code not passing? It seems correct!

I'm doing https://teamtreehouse.com/library/javascript-basics-2/working-with-numbers/using-math-methods

In challenge task 2, according to me, it should work.

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

But it's not!

script.js 
var temperature = 37.5;

alert(Math.floor(temperature));

Hi Santosh,

Do you still have the code in from task 1? I just checked it on my end and it worked fine with the following code.

var temperature = 37.5

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

Yes, The previous code needs to be there.

The code is correct, but you need to use Math.round instead of Math.floor()

We're rounding the number up instead of down. :-)
