Javascript Math
The JavaScript math object provides several constants and methods to perform mathematical operation. They are following :
Javascript Math.abs() :
``````<html>
<title>Javascript Math.abs()</title>
<body>

<h4>Absolute value of -9 is : <span id="abs_val"></span>   </h4>

<script type="text/javascript">

document.getElementById('abs_val').innerHTML=Math.abs(-9);

</script>
</body>
</html>``````
Output :

#### Absolute value of -9 is : 9

Javascript Math.ceil() :
``````<html>

<script type="text/javascript">

var value = Math.ceil(17.95);
document.write("First Value : " + value );

var value = Math.ceil(17.20);
document.write("<br />Second Value : " + value );

var value = Math.ceil(-9.95);
document.write("<br />Third Value : " + value );

var value = Math.ceil(-9.20);
document.write("<br />Fourth Value : " + value );

</script>
</body>
</html>``````
Output :

First Value : 18

Second Value : 18

Third Value : -9

Fourth Value : -9

Javascript Math.floor() :
``````<html>

Fourth Value : -3

Javascript Math.max() and Math.min() :
``````<html>
<title>Javascript Math.max() and Math.min()</title>
<body>

<script type="text/javascript">

//Maximum Value
var value = Math.max(2, 13, -8, 27);
document.write("First Max Value : " + value );

var value = Math.max(-1, -16, -5);
document.write("<br />Second Max Value : " + value );

var value = Math.max(0, -5);
document.write("<br />Third Max Value : " + value );

//Minimum value
var value = Math.min(2, 13, -8, 27);
document.write("<br /><br />First Min Value : " + value );

var value = Math.min(-1, -16, -5);
document.write("<br />Second Min Value : " + value );

var value = Math.min(0, -5);
document.write("<br />Third Min Value : " + value );

</script>
</body>
</html>``````
Output :
