14 Facts About Fortran

Fortran is a general-purpose, compiled imperative programming language that is especially suited to numeric computation and scientific computing.

Fortran was originally developed by IBM in the 1950s for scientific and engineering applications, and subsequently came to dominate scientific computing.

Fortran has had numerous versions, each of which has added extensions while largely retaining compatibility with preceding versions.

Fortran's design was the basis for many other programming languages.

Since August 2021 Fortran has ranked among the top 15 languages in the TIOBE index, a measure of the popularity of programming languages.
