# Javascript math object tutorial

## Javascript math object:

A JavaScript Math object provides no. of properties and methods for performing mathematical operations. Math is not a constructor and all the properties and methods of Math are static.

## Example:

    <script> var num = Math.random(); var squarRoot = Math.sqrt(num ) ; document.write("Random Number: " + num + "</br>"); document.write("Square root: " + squarRoot ); </script>

## JavaScript Math Object Properties:

 Property Description E \ Euler’s constant and the base of natural logarithms, approximately 2.718. LN2 Natural logarithm of 2, approximately 0.693. LN10 Natural logarithm of 10, approximately 2.302. LOG2E Base 2 logarithm of E, approximately 1.442. LOG10E Base 10 logarithm of E, approximately 0.434. PI Ratio of the circumference of a circle to its diameter, approximately 3.14159. SQRT1_2 Square root of 1/2; equivalently, 1 over the square root of 2, approximately 0.707. SQRT2 Square root of 2, approximately 1.414.
