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 be calculate the sum of infinite series: $e=1+{\frac {1}{1}}+{\frac {1}{1.2}}+{\frac {1}{1.2.3}}+{\frac {1}{1.2.3.4}}+...$
And the inverse function of the natural logarithm function is the exponential function:

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