# Python Number log() Function

## Description:

This function returns natural logarithm of x, for x > 0.

## Syntax:

    import math

    math.log( x )

Note: This function is not accessible directly so we need to import math module and then we need to call this function using math static object.

## Parameters:

Here is the detail of parameters:

- x: This is a numeric expression.

## Return Value:

The natural logarithm of x, for x > 0

## Example:

    #!/usr/bin/python
    import math   # This will import math module

    print "math.log(100.12) : ", math.log(100.12)
    print "math.log(100.72) : ", math.log(100.72)
    print "math.log(119L) : ", math.log(119L)
    print "math.log(math.pi) : ", math.log(math.pi)

This will produce following result:

    math.log(100.12) :  4.60636946656
    math.log(100.72) :  4.61234438974
    math.log(119L) :  4.77912349311
    math.log(math.pi) :  1.14472988585
