[Fortran Tuto 3] Simple Math and Real Variables

[@claushelge1366]

Great to see that someone does Fortran tutorials these days. I recently started working in public statistics and now I am on the lookout for fast languages for statistics and big data. I read that despite its age Fortran might be an interesting candidate.

great tutorial. Very good job. Thanks a bunch for very good pronunciation. My father was using Fortran in 70th....Ist possible to obtain your examples ?

[@rmonier75]

Thank you for your tutorials. Which book do you recommend to learn fortran 90 ? I seem to remember that you show a book in Tutorial 1 or 2. Many thanks.

Hello, can you do calculations with a variable "x" that has no value? and the output of the calculations is in function of x? so that later you can define x and get the result?

[@Feaforall]

That’s called a subroutine in Fortran. There’s a video about it in the series

[@kevin_mitchell]

There's no need to change x to a real. You can still do real division as long as one of the operands is a real: change the 3 to 3.0, or multiply the integer variable 'x' by 1.0: y = x / 3.0 y = x * 1.0 / 3
