Code Challenge: Syntax Error?

I am currently trying to complete a code challenge in the numbers section of JS. The following code should give me an alert showing a rounded down version of a decimal number:

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

Where am I going wrong with this? I checked MDN and I can't see where I might have made an error.

Hey ! you just have to call the alert dialog two times.

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

With your code, you should get the alert box with rounded to floor temperature variable.

But why are you assigning call of alert box to temperature variable?

After that call temperature will get value of undefined, since it is the return value of alert function.

Just call it like:

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

yeah but the challenge is asking a double alert ( from Task 1 ) if she does it one time, she will have a bummer telling the first task doesnt seem to work ! other than that, you re totally right Grant Gasparyan
