I don't think this is the case: $ cat foo.f90 program main real(kind=8) :: a integer(kind=8) :: n n = 2_8**32 a = 1_8 + epsilon(a) print *,a**n end program main $ gfortran foo.f90 $ ./a.out 1.00000095367477 I do admit this is a corner case, though :-) -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=30834
