# Random number Math function

Random numbers are required in different scripts like game, dice and many other applications. We can use JavaScript math function random() to generate random number between 0 and 1. We will use this function to generate random numbers between other ranges also. Here is the syntax
``math.random(number);``
The return value from this function is random number between 0 and 1. As we have to remove the decimal part to get random numbers between 0 to 10.

We will multiply the random number returned by math.random() by 11 and then take the floor value of it to get the random number. We have used floor value as this function returns the lower integer part only. If we use round function then the value will be adjusted to nearest integer so floor function gives more accurate random number.

Here is the demo of random number generator.

Here is the total code of this demo.
``````
<html>
<title>(Type a title for your page here)</title>

<script type="text/javascript">
function generate(){
var my_num=Math.random();
document.f1.t1.value=(my_num*11);q
document.f1.t2.value=Math.floor(my_num*11);q
}
</script>

<body >
<form name=f1>
Random number after multiplying with 11
<input type=text name=t1>
<br>After taking the floor value
<input type=text name=t2>

<input type=button value='Display' onClick='generate()';>
</form>

</body>
</html>
