I missed that part of the output. The exceeding
long string of digits caught my attention. Can
you submit a PR? The problem, I believe, is in
gfc_simplify_nint where it indeed does the adding
and substraction of 0.5 depending on the sign of
y and truncation. I converted gfortran to use MPFR,
and I missed the opportunity to clean up this function.
