A community-driven de facto standard library for Fortran, providing utilities, algorithms, and mathematical routines missing from the ISO Fortran standard. It serves as both a specification and reference implementation, developed in cooperation with the Fortran Standards Committee.

Use cases

• add linear algebra and sparse matrix routines to a Fortran project
• get string manipulation and containers in Fortran without writing them myself
• run unit tests and assertions in Fortran code
• generate random numbers and compute statistics in Fortran
• perform numerical integration and FFT in Fortran
• sort and search arrays in Fortran
• build a Fortran project with fpm or CMake using a standard library

When to choose

• you write modern Fortran (2008+) and want well-vetted common utilities and math routines
• you want a NumPy-like set of numerical tools in pure Fortran
• you want a library aligned with the Fortran standards committee's direction

When to avoid

• you need a mature, feature-complete standard library today - parts are still work in progress
• your compiler only supports pre-2008 Fortran
• you need domain-specific libraries beyond the current scope (e.g., plotting, networking)
