Lately I have been learning the old programming language, Fortran. I don’t particularly like Fortran or plan to use it, but I have run out of things to learn about C++, Java, Python, or C#. So far I have learned how to work with numbers, loops, and arrays. Today I have learned how to work with strings. Formatting numeric output in Fortran is a little tricky so I will have to create a separate topic in my notes for that. I am running Fortran using GNU Fortran or GFortran which is part of my Cygwin installation.
The only mildly useful thing I have learned so far is that Fortran supports complex numbers. I have been working with complex numbers to reproduce some geometric designs which are based on the complex plane. I have been improving my math skills and learning Fortran may help with that since this programming language is mainly used for science.
