Math.floor

Why I can't use Math.floor?

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

It wants you to have 2 alerts, One thats rounded and the other floor. I suggest putting each in their own variable.

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

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

A rounded and floor temperature needs to be displayed

const temperature = 37.5;
[Math.round(temperature), Math.floor(temperature)].forEach(alert)
