# exp(x) fortran

In Fortran, the `exp(x)`

function is used to calculate the exponential value of `x`

. The `exp(x)`

function returns the exponential value of `x`

, where `x`

is a real or complex number. Here is an example code snippet showing how to use the `exp(x)`

function in Fortran:

```
program exponential_example
real :: x, result
! Assign a value to x
x = 2.0
! Calculate the exponential value of x
result = exp(x)
! Print the result
print *, "The exponential value of", x, "is", result
end program exponential_example
```

In this example, the program assigns the value `2.0`

to the variable `x`

. It then uses the `exp(x)`

function to calculate the exponential value of `x`

, and stores the result in the variable `result`

. Finally, it prints the value of `result`

.

You can modify the value of `x`

to calculate the exponential value for different numbers. Remember to include the `use, intrinsic :: iso_fortran_env`

statement at the beginning of your code if you are using a Fortran version older than Fortran 2008, as the `exp()`

function is part of the intrinsic module.
