Modern Fortran Machine Constants Module (r1mach, d1mach, i1mach).

Status

Compiling

A Fortran Package Manager manifest file is included, so that the library and test cases can be compiled with FPM. For example:

fpm build --profile release
fpm test --profile release

To use fortran-mach within your fpm project, add the following to your fpm.toml file:

[dependencies]
fortran-mach = { git="https://github.com/jacobwilliams/fortran-mach.git" }

Or, to use a specific version:

[dependencies]
fortran-mach = { git="https://github.com/jacobwilliams/fortran-mach.git", tag = "0.1.0" }
