JAVASCRIPT NATIVE OBJECT-MATH OBJECT PAGE(2)

Math Methods:
1.     Math.abs(x)-  Returns the absolute value of a number.
Syntax:     Math.abs( x ) ;
Example:
<script type="text/javascript">
 var value = Math.abs(-1);
document.write("First  Value : " + value ); 
  var value = Math.abs(null);
document.write("<br />Second Value : " + value ); 
 var value = Math.abs(20);
document.write("<br />Third  Value : " + value ); 
 var value = Math.abs("string");
document.write("<br />Fourth  Value : " + value ); 
</script>

Output:   
First  Value : 1
Second Value : 0
Third  Value : 20
Fourth  Value : NaN
