Modern Fortran explained: incorporating Fortran 2018 (pdf)

Description

This edition of Modern Fortran Explained expands on the last. Given the release of updated versions of Fortran compilers, the separate descriptions of Fortran 2003 and Fortran 2008 have been incorporated into the main text, which thereby becomes a unified description of the full Fortran 2008 version
of the language. This clearer standard has allowed many deficiencies and irregularities in the earlier language versions to be resolved.

Four new chapters describe the additional features of Fortran 2018, with its enhancements to coarrays for parallel programming, interoperability with C, IEEE arithmetic, and various other improvements.

Written by leading experts in the field, two of whom have actively contributed to Fortran 2018, this is a complete and authoritative description of Fortran in its latest form. It is intended for new and existing users of the language, and for all those involved in scientific and numerical computing.
It is suitable as a textbook for teaching and, with its index, as a handy reference for practitioners.
