LN(n)

This function gives the Natural Logarithm of a number.
$LN$ is the logarithm in which the base is the irrational number $e$ ( $e$ = 2.71828...).
For example, $ln_{1}0=loge_{1}0\approx 2.30258$
Also called Napierian logarithm.
The constant $e$ is called Euler's number.
The Natural Logarithm is denoted by $ln(x)$ or $loge(x)$ .
where $x$ is the Positive real number.
The ln(x) is the inverse function of the exponential function e^ln(x)=x if x>0.

ln(e^x)=x
