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

Open an alert dialog a second time and display the temperature variable rounded downward to the nearest integer. You'll need to check the Mozilla Developer Network to find the proper Math method for this (hint: down is toward the "floor".)

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

the challenge gives you a pretty good hit. "floor" So you'll need to add an additional alert but this time with the Math.floor method

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

I hope this helps.

Hi! You have to substitute the Math.round() method with Math.floor() to rounded downward the variable! https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Math/floor

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

var tempRounded = Math.round(temperature); var tempRoundDown = Math.round(temperature);
