Object: Math
Method: Random
Math.random() will create a decimal number between 0 and 1 (e.g: 0.833556767).
We have to use the following procedure to convert the decimal number to a random number of use.
Creating a random number less than a value:
To create a random number less than any value, we will have to use two functions, random and round of Math object.
For an example we will try to create a random number less than 1000
Example:
<script language=javascript>
var xx = Math.random();
var rnumber = Math.round(xx*1000);
document.write(rnumber);
</script>
Result:
In the above example,
First a random decimal number was created using Math.random()
Now we multiply it with the number below which we want random number to be.
Pass is as the argumnet to Math.Round to remove the decimal points.
If we would want a number below 100, we would have to use 100 instead of 1000.
