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. -- Steve
