Fortran (/ ˈ f ɔːr t r æ n /; formerly FORTRAN) is a third-generation, compiled, imperative programming language that is especially suited to numeric computation and scientific computing.

Fortran is a natively parallel programming language with intuitive array-like syntax to communicate data between CPUs. You can run almost the same code on a single CPU, on a shared-memory multicore system, or on a distributed-memory HPC or cloud-based system.

Apr 8, 2025 · FORTRAN, computer programming language created in 1957 by John Backus that shortened the process of programming and made computer programming more accessible. FORTRAN enabled the rapid writing of computer programs that ran nearly as efficiently as programs that had been laboriously hand coded in machine language.

Oct 26, 2022 · The purpose of the GNU Fortran (GFortran) project is to develop the Fortran compiler front end and run-time libraries for GCC, the GNU Compiler Collection. GFortran development is part of the GNU Project. We seek to bring free number crunching to a broad spectrum of platforms and users.

Fortran is designed primarily for numerical calculations, and it has many built-in functions for mathematical operations. In the example triangle-area program, we use the basic functions: +, -, *, / for addition, subtraction, multiplication, and division.

This quickstart tutorial gives an overview of the Fortran programming language and its syntax for common structured programming concepts including: types, variables, arrays, control flow and functions.
