WebApr 29, 2011 · In Fortran, subroutines are generally used much more frequently than functions.

Subroutines are more flexible since they can have any number of inputs and outputs. Sorted by: 9. The recommended way to do this in modern Fortran would be to create a module, let's call it e.g. "mymath". In that case, you can create one file mymath.f90 containing something like this: module mymath contains function myfunction (x) result (r) real, intent (in) :: x real :: r r = sin (x) end function end module. cookies \u0026 ice cream dome cake https://florentinta.com
