WebThe following uses two Fortran intrinsic functions MIN () and MAX (). It is a count-down loop. The initial-value is the maximum of a, b and c, the final-value is the minimum of a, b and c, and the step-size is -2. Therefore, if the READ statement reads 2, 7, 5 into a, b and , then MAX (a,b,c) and MIN (a,b,c) are 7 and 2, respectively. http://www.personal.psu.edu/jhm/f90/lectures/15.html

WebJun 26, 2011 · In FORTRAN i was the first letter to default to the integer type. The full range of implicit integer types were any starting with the letters i to n. Working with loops for three dimensions got us i, j, and k. The pattern continued for additional dimensions. WebApr 5, 2024 · However, FORTRAN 77 does use line numbers (called labels) for certain instructions, including the FOR loop. Although in FORTRAN 77, the FOR is actually called a DO loop, it does the same thing and has almost the same usage. In FORTRAN 77, the DO loop syntax looks like this: DO label var = start, end. WebThe habit of using letters from the end of the alphabet (...,x,y,z) for unknown variables and from the beginning (a,b,c...) for constants is generally attributed to Rene Descartes, (see also here) so I assume i,j,k...n (in the middle of the alphabet) for integers is likely due to him too.

WebWith n=1, the default, no loops are unrolled automatically by the optimizer. With n greater than 1, the optimizer attempts to unroll loops up to a depth of n. The compiler's code generator makes its decision to unroll loops depending on a number of factors. The compiler might decline to unroll a loop even though this option is specified with n>1.
