Drawing blanks as to how to convert the second alert to show the "rounded down" integer value of the temperature variable. I probably need to make another variable for this second alert?

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

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

It worked!. Did not think I could have the variable in another set of parentheses in the set of parentheses for the alert command. Thanks for the help.

Or you could try calling the Math.round() and Math.floor() functions within alert() function. It'll look something like

alert(Math.round(myNumber));
