2. Math.random()
• This function is used to return a floating-point
pseudo-random number between range [0,1) ,
0 (inclusive) and 1 (exclusive).
• This random number can then be scaled
according to the desired range.

4. Generating a random floating point number
between 0 and a specified max
• var x = Math.random()*10;
<html>
<body>
<h1>example</h1>
<h1>
<script>
var x = Math.random()*10;
document.write(x);
</script>
</h1>
</body>
</html>

5. <html>
<body>
<h1> example</h1>
<h1>
<script>
var x = Math.floor(Math.random()*10);
document.write(x);
</script>
</h1>

</html>
The Math.floor() method rounds a number
DOWNWARDS to the nearest integer, and
returns the result. Dr.T.Abirami/KEC
6. Generating a random floating point
number within a range
var min = 83.1;
var max = 193.36;
var x = Math.random()*(max - min)+min;
console.log(x); // 126.94014012699063

7. Example 1: This example generate an integer
random number between 1(min) and 6(max).
<script>
function randomNumber(min, max) {
return Math.random() * (max - min) + min;
}
document.write("Random Number between 1 and 6: ")
document.write( randomNumber(1, 6) );
</script>
