The Math object allows you to perform mathematical tasks on numbers.
The Math object includes several mathematical methods.
One common use of the Math object is to create a random number:
<!DOCTYPE html>
<html>
<body>
<p>Math.random() returns a random number between 0 and 1.</p>
<button onclick="myFunction()">Try it</button>
<p id="demo"></p>
<script>
function myFunction() {
document.getElementById("demo").innerHTML = Math.random();
}
</script>
</body>
</html>
Math.min() and Math.max()
Math.min() and Math.max() can be used to find the lowest or highest value in a list of argument
Math.min(0, 150, 30, 20, -8, -200); // returns -200
Math.random()
Math.random() returns a random number between 0 (inclusive), and 1 (exclusive):
Math.random(); // returns a random number
Math.round()
Math.round() rounds a number to the nearest integer:
Math.round(4.7); // returns 5
Math.round(4.4); // returns 4
Math.ceil()
Math.ceil() rounds a number up to the nearest integer:
Math.ceil(4.4); // returns 5
Math.floor()
Math.floor() rounds a number down to the nearest integer:
Math.floor(4.7); // returns 4
