<html>
<body>
<p>Values:</p>
<script>
var myFloat = 1.5;
var myTrunc = Math.trunc( myFloat );
var myCeil = Math.ceil( myFloat );
var myFloor = Math.floor( myFloat );
var myRound = Math.round( myFloat );
document.write(myTrunc+ " ");
document.write(myCeil+ " ");
document.write(myFloor+ " ");
document.write(myRound+ " ");
</script>
</body>
</html>
