You need to be more clear on your question. What have you tried? What is it expecting? What errors are you receiving?

We can't help you if we don't know where, how, or why you are having problems.

You need to call the round() method on temperature and put that into an alert.

this worked for me. Math.round() rounds to the nearest integer.

alert(Math.round(temperature))

This resolves it:

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