How can I write a program in FORTRAN 90 that determines the machine epsilon in any computer ?

     type ErrorOrT[M[+_], A] = EitherT[M, Throwable, A]
type ErrorOr[A] = ErrorOrT[IO, A]

You'd read to the back of your favourite Fortran reference where you'd find the intrinsic function epsilon

And, if you think the code you've posted is Fortran you've been misled.
