## Fortran

a programming language; more precisely, a family of such languages that evolved from the original version developed in 1957 in the USA under the supervision of J. W. Backus. The name derives from “formula translation,” referring to the translation of programs written in FORTRAN into machine language. FORTRAN contains statements for assignment, conditions, cyclic operation, subroutines, storage allocation, and real and complex variables, which may have logical, integer, real, or complex values; it also includes highly developed statements for input-output. FORTRAN is the most widely used programming language for scientific and engineering calculations. The language’s specifications are fixed in several national and international standards.

## FORTRAN

[′fȯr‚tran] (computer science)

A family of procedure-oriented languages used mostly for scientific or algebraic applications; derived from formula translation.

## Fortran

(language)(Formula Translation) The first and, for a long
time, the most widely used programming language for numerical
and scientific applications. The original versions lacked
recursive procedures and block structure and had a
line-oriented syntax in which certain columns had special
significance.

There have been a great many versions.

The name is often written "FORTRAN", harking back to the days before computers were taught about lower case, but ANSI decreed, in about 1985 via the ANSI FORTRAN Technical Committee TC, that it should be "Fortran".

## FORTRAN

(**FOR**mula

**TRAN**slator) The first high-level programming language and compiler, developed in 1954 by IBM. It was originally designed to express mathematical formulas, and although it has been used for business applications, it is primarily used for scientific, engineering and mathematical problems. FORTRAN IV is an ANSI standard, but FORTRAN V has various proprietary versions. The following FORTRAN example converts Fahrenheit to Celsius:

write(6,*) 'Enter Fahrenheit ' read(5,*) XFAHR XCENT = (XFAHR - 32) * 5 / 9 write(6,*) 'Celsius is ', XCENT stop end
