Some commonly used Math function in Java Script

•  Math.PI  :   Math.PI property gives value of PI.
• Math.sqrt(<value>)  : Math.sqrt(<value>) method returns square root of number passed to its parameter.
• Math.round(<double value>)   : Math.round(<double value>) returns an round of value of given decimal value. Such as round of value of 5.7 is 6.
• Math.random()   :  Math.random() method return random number which is greater than 0 and less than 1.

Following function provides a demonstration to use Java Script Math object

<script type="text/javascript">
        function mathLibrary() {
            document.write("Value Of Pie is--->  : " + Math.PI + "<br />");
            document.write("Squareroot of 81 is---->  : " + Math.sqrt(81) + "<br />");
            document.write("Value of Sin 60 is---->  :  " + Math.sin(60) + "<br />");
            document.write("Round of 5.7 is --->   : " + Math.round(5.7) + "<br />");
            document.write("Random number generated by Java Script is---->  :" + Math.random() + "<br />");
        }
</script>

Output of the following code snippet is as follows
