Fortran
Sign in to saveFortran (; formerly FORTRAN) is a third-generation, compiled, imperative programming language designed for numeric computation and scientific computing.
AI overview
Fortran is a programming language created specifically for performing mathematical calculations and scientific research, where a computer converts the human-readable code into machine instructions before running it. It remains important because it has been widely used for decades in fields like physics, engineering, and weather prediction, where handling large numerical computations efficiently is critical.

Fortran (; formerly FORTRAN) is a third-generation, compiled, imperative programming language designed for numeric computation and scientific computing.
Fortran was originally developed by IBM with a reference manual being released in 1956; however, the first compilers only began to produce accurate code two years later. Fortran computer programs have been written to support scientific and engineering applications, such as numerical weather prediction, finite element analysis, computational fluid dynamics, plasma physics, geophysics, computational physics, crystallography and computational chemistry. It is a popular language for high-performance computing and is used for programs that benchmark and rank the world's fastest supercomputers.
