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.
