If you want to learn #Fortran or to upgrade your knowledge to the latest Fortran standards, this #book is excellent:
- Curcic, Milan (2019). "Modern Fortran: Building Efficient Parallel Applications". Manning Publications.
The following book is a reference for Fortran programmers, more readable than the standard:
- Metcalf, M., J. Reid, and M. Cohen (2018). "Modern Fortran Explained: Incorporating Fortran 2018". Oxford University Press.
Both include Fortran 2018 novelties.
