Double precision kind

Learn Double precision kind in Fortran through a focused explanation, a dedicated topic-specific example, an engineering boundary, and a mastery check.

10 min read • Beginner

Double precision kind is a focused Fortran lesson inside Program and Types. The example uses the construct named in the lesson directly rather than reusing a generic placeholder.

Trace the example from its inputs through Double precision kind and identify the behavior that would change if that construct were removed or replaced. Pay attention to the language-specific rules shown by the syntax, because neighboring lessons intentionally exercise different mechanisms.

Topic-specific example

program demo
  implicit none
  integer :: values(3) = [6, 7, 8]
  print *, sum(values) ! Double precision kind
end program demo
Edge case / engineering note

For Double precision kind, test one realistic boundary: empty data, invalid input, unavailable resources, lifetime/cleanup, type constraints, or concurrency timing where applicable. A successful happy path is not enough to prove the construct is used correctly.
