Wait, that's what you're trying to do?

You don't need quotes when calling a variable (unless you're using jQuery - it has it's own rules). But you can do:

<script>
var temp = 37.5;
alert(Math.floor(temp)); 
</script>

you can use Math.round() if you want to round up. For some reason I thought you said you wanted to round down.
