Javascript Tips #2 : Using Mathematical Constants In Javascript

Note down following thing -

1. The Math object allows you to perform mathematical tasks.
2. We can access JavaScript Object and its methods to access the mathematical constants.

We can Access Following Properties

Property	Description	Value(Approx)
E	Euler's number	2.718
LN2	Natural logarithm of 2	0.693
LN10	Natural logarithm of 10	2.302
LOG2E	Base-2 logarithm of E	1.442
LOG10E	Base-10 logarithm of E	0.434
PI	PI	3.14
SQRT1_2	Square root of 1/2	0.707
SQRT2	Square root of 2	1.414

Sample Program :

<script language="JavaScript">
<!--
    var radius;
    radius = 3;
    document.write(Math.PI * ((radius)*(radius)));
// -->
</script>
