When was Fortran developed?
Fortran was originally developed by IBM in the 1950s for scientific and engineering applications, and subsequently came to dominate scientific computing. It has been in use for over six decades in computationally intensive areas such as numerical weather prediction, finite element analysis, computational fluid dynamics, geophysics, computational physics, crystallography and computational chemistry. It is a popular language for high-performance computing and is used for programs that benchmark and rank the world's fastest supercomputers.
When was Fortran 2008 approved?
ISO/IEC 1539-1:2010, informally known as Fortran 2008, was approved in September 2010. As with Fortran 95, this is a minor upgrade, incorporating clarifications and corrections to Fortran 2003, as well as introducing some new capabilities. The new capabilities include:
What is a FORTRAN 3?
A reproduction of a FORTRAN coding form, printed on paper and intended to be used by programmers to prepare programs for punching onto cards by keypunch operators. Now obsolete. IBM also developed a FORTRAN III in 1958 that allowed for inline assembly code among other features; however, this version was never released as a product.
What is the FORTRAN compiler?
FORTRAN was provided for the IBM 1401 computer by an innovative 63-phase compiler that ran entirely in its core memory of only 8000 (six-bit) characters. The compiler could be run from tape, or from a 2200-card deck; it used no further tape or disk storage. It kept the program in memory and loaded overlays that gradually transformed it, in place, into executable form, as described by Haines. This article was reprinted, edited, in both editions of Anatomy of a Compiler and in the IBM manual "Fortran Specifications and Operating Procedures, IBM 1401". The executable form was not entirely machine language; rather, floating-point arithmetic, sub-scripting, input/output, and function references were interpreted, preceding UCSD Pascal P-code by two decades.
What was the main enhancement of Fortran II?
IBM's FORTRAN II appeared in 1958. The main enhancement was to support procedural programming by allowing user-written subroutines and functions which returned values with parameters passed by reference. The COMMON statement provided a way for subroutines to access common (or global) variables. Six new statements were introduced:

Why is Fortran so popular?
A main reason for Fortran's popularity was that it used to be the teaching language for these students.
What are the advantages of Fortran?
An advantage with Fortran is it’s built-in array slicing syntax, combined with how it lays out memory, and the default use of non-aliasing. First, the memory layout. In C and C++ a two dimensional array is by default an array with contains pointers to other arrays.
Why is Fortran used in science?
Part of that is because of habit, part is because it has a syntax that makes some things slightly easier than with other languages (when it comes to dealing with arrays, matrices or complex numbers, for example) and finally part is because some of the most important libraries for linear algebra, Lapack, Blas and Arpack, have been written natively in Fortran and are supposedly optimised best for Fortran. When performance is critical in these sort of tasks, Fortran used to be the fastest language available. I’m not sure if it has now been caught up by C++ or not.
What is Fortan used for?
It is used for scientific computing . I will not go into explanations what are its strengths when it comes to vector and matrix manipulation as it was covered by other contributors. One of the strengths of Fortan when used in scientific computing is that its syntax is simple and clean so a scientist can put more focus on scientific problem she or he is watching rather than contemplating on intricacies of C/C++ (Shall I make it pointer, or a reference? Shall I declare this function as a “const” or not? Oh yes, don’t forget, arrays start from 0, not from 1 as humans did from the dawn of civilizat
What is XL Fortran for Linux?
XL Fortran for Linux, V15.1.4, for little endian distributions released in 2016 supports the CUDA Fortran programming model, which is a subset of CUDA constructs, to exploit the NVIDIA GPUs. You can use the commonly used subset of CUDA Fortran that is provided by the compiler to offload computations to the NVIDIA GPUs.
What model does Manila Observatory use?
Close to home. The folks at the The Manila Observatory heavily use MM5 Community Model for climate studies. Huge chunks of the code base is primarily in FORTRAN.
Does Fortran use vectorized arrays?
Third, since Fortran by default turns off aliasing of arrays and all arrays are by default vectorized, it becomes much easier for compiler writers to optimize operations. Having compared matrix multiplication operations in various programming languages I can testify that Fortran has easily outperformed them all.
How old is Fortran?
Fortran Today. Fortran is now over forty years old and remains the top language in scientific and industrial programming—of course, it has constantly been updated. The invention of Fortran began a $24 million dollar computer software industry and began the development of other high-level programming languages.

Is Compilers Update 6 available?
Compilers Update 6 and 7 are not available to the general public.
Does Fortran have a private statement?
Previous compiler versions erroneously permitted a PRIVATE or SEQUENCE statement to appear prior to the declaration of any type parameters in a derive type declaration. Intel® Fortran Compiler 19.0.3 no longer permits this behavior.
Why is Fortran used?
FORTRAN is traditionally used for scientific/engineering numerical computing for reasons of inertia as much as anything else, as well as having lots of specialized libraries. FORTRAN, like C, is a "super assembler" that lets you get close to the metal without adding a lot of fluff to make programming easier, or protect you from yourself -- Programming for Real Men(tm). It has a very long history of compiler optimization work, but there's no reason that other languages can't use most of those optimizations. It was designed before there was real language/compiler science, and shows its age.
What are the downsides of Fortran?
The downsides of Fortran are mainly the flip side of one of the upsides mentioned; Fortran has a huge long history. Upside: tonnes of great libraries. Downsides: tonnes of historical baggage.
What is Fortran science?
Fortran is what a lot of scientists have been taught with and what a lot of the libraries they need are implemented in. A number of them might not be computer scientists or IT people, more computational scientists. Their primary goal is rarely computing, it's their science first.
Is Fortran a good language to write a web browser?
If you have to do a lot of number crunching, Fortran remains one of the top choices, which is why many of the most sophisticated simulation codes run at supercomputing centres around the world are written in it. But of course it would be a terrible, terrible, language to write a web browser in. To each task its tool.
Is Fortran a procedural language?
Fortran is a 1960's procedural based language with very little in the way of modern language features. Arguably it is Basic on steroids (yes I know it predates Basic) with little concept of scope, algorithmic control structures and a rudimentary I/O model. The lack of variable initialization checking for example allegedly was responsible for the loss of a US satellite (misspelled variable name).
