Example2:
Use the JavaScript Math.floor() method on different numbers:
<!DOCTYPE html>
<html>
<body>
<button onclick="floorMethod2()">Try it</button>
<p id="example-2"></p>
<script>
function floorMethod2() {
var a = Math.floor(0.80);
var b = Math.floor(0.95);
var c = Math.floor(4.2);
var d = Math.floor(6.1);
var e = Math.floor(-8.9);
var f = Math.floor(-3.3);
var x = a + "," + b + "," + c + "," + d + "," + e + "," + f;
document.getElementById("example-2").innerHTML = x;
}
</script>
</body>
</html>
