I believe there is a bug in the site var temp = Math.floor(temperature); alert(temp); Fails the test case

I believe there is a bug in the site var temp = Math.floor(temperature); alert(temp); Fails the 2nd test case

while var temp = Math.round(temperature); alert(temp); works!

In the second, I get the proper alert from my browser which displays 37.

script.js 
var temperature = 37.5;
index.html

Rounded, 37.5 would be 38. Try this:

var temperature = 37.5;
alert(Math.round(temperature,0));

And this for Task 2:

alert(Math.floor(temperature));

Thank you! I figure out my error. My error was that I did not have both cases at the same time. I simply changed Math.round to Math.round in stead of re-write another function call!
