F

F is a modular, compiled, numeric programming language, designed for scientific programming and scientific computation.

F was developed as a modern Fortran, thus making it a subset of Fortran 95.

It combines both numerical and data abstraction features from these languages.

F is also backwards compatible with Fortran 77, allowing calls to Fortran 77 programs.

F was implemented on top of compilers from NAG, Fujitsu, Salford Software and Absoft.

It was later included in the g95 compiler.
