# EXP function

## Description

Natural exponential function. EXP(x) returns the natural exponential of x.

$$\exp(x) = e^x$$

where e is the base of the natural logarithm, 2.718281828459… (Euler's number).

EXP is the inverse function of the LN function.

$$\exp(1)=2.718281828459$$ $$\ln(2.718281828459)=1$$

In MedCalc, Euler's number is returned by the E() function.

$$\ln(E())=1$$

## Example
