EXP(x)

This function gives the $e$ raised to the power of number.
In $EXP(x)$ , where $x$ represents the exponent of $e$ , or $e^{x}$ .
The approximate value of the constant $e=2.718281828459045$ and it is equal to $e^{x}$ or $EXP(1)$ .
It is called the Mathematical Constant or Euler's Number or Napier's Constant.
It is the base of natural logarithm.
It can calculate the sum of infinite series: $e=1+(1/1)+(1/1.2)+(1/1.2.3)+(1/1.2.3.4)+...$
And the inverse function of the natural logarithm function is the exponential function:

$f^{-1}(x)=e^{x}$ .
