WebFortran was originally developed by a team at IBM in 1957 for scientific calculations. Later developments made it into a high level programming language. In this tutorial, we will learn the basic concepts of Fortran and its programming code. Audience This tutorial is designed for the readers who wish to learn the basics of Fortran. Prerequisites Web• Same form as the specification part of a Fortran program plus: – The type of the function if this has not been included in the function heading. – The type of each formal argument. • INTENT specifier: tells how the arguments are to transfer information. • Execution section has same form as Fortran program plus: chase bank closing accountsWebFortran 77 also has some intrinsic (built-in) functions. A simple example illustrates how to use a function: x = cos(pi/3.0) Here cos is the cosine function, so x will be assigned the value 0.5 (if pi has been correctly defined; Fortran 77 has no built-in constants). There are many intrinsic functions in Fortran 77. Some of the most common are: chase bank close account
