Summary

Summary

The success of Fortran as the predominant language in the field of scientific and numerical computing is due, in part, to its steady evolution. Following the publication of standards in 1966, 1977 and 1991, the committee responsible for their development, J3, worked in conjunction with an ISOcommittee to enhance Fortran 90, as the 1991 standard was known, creating Fortran 95. Fortran 95 was published in 1997, and, in addition to Fortran 90's new features for array processing, abstract data types, modules, and pointers, it contains additional features to keep it aligned with HighPerformance Fortran, as well as some minor enhancements.This volume represents a revision of the first edition of Fortran 90/95 Explained. The Fortran 95 material is now fully integrated with that of Fortran 90, while maintaining a clear distinction between the two language levels. Chapters on enhanced data type facilities and floating-point exceptionhandling, two optional enhancements to Fortran 95, have been added. It is a complete and authoritative description of Fortran 90/95, and is intended for new and existing users, and for all those involved in scientific and numerical computing.


Author Notes

Michael Metcalf worked for many years at CERN, Geneva. He is the author of a range of publications, including the books The F programming language and Effective Fortran 77 (Oxford University Press), and FORTRAN Optimization (Academic Press). He was the Editor of the Fortran 90 standard.Professor Michael Metcalf, Karntner Ring 10 1010 Vienna Austria Tel: 0043 1503 7940 John Reid is an independent contractor and is well known as a numerical analyst: he is a co-author of Direct methods for sparse matrices (Oxford University Press). He served as Secretary of X3J3 and played aleading role in the development of Fortran 90, Fortran 95, and the exception-handling extensions. Professor J.K.
