Hi, You have used the commas ' ' with the number so you received a string instead of a number. Try this..

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

I entered this into my JavaScript console and an alert box popped up that said 38.

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