Swap two numbers
Subroutine to swap two integers:
Absolute path
Here is a function to convert filenames to their absolute path:
Calculate hypotenuse
Hypotenuse can be calculated using following formula:
Numerical integration
We will calculate the area under the curve $f(x)$ within the bounds $x=a$ and
Haversine formula
Determine the distance between two places on earth given latitude and longitude.
Inner product
Example of dynamic array allocation:
Monte Carlo method
We will approximate value of $\pi$ by Monte Carlo method. We will generate
Monte Carlo integration
Time
Following example uses dateandtime and cpu_time to find current date and
Argument parsing
We will use commandargumentcount and getcommandargument to parse command
External command
We can call executecommandline to execute external commands in a FORTRAN
