I don't have a reference as good as the Fortran standard, but Steve Lionel said in Dr. Fortran [*] that DOUBLE PRECISION is still part of the standard fixed-form syntax. > COMPLEX(KIND=8) This could be particularly problematic if you're trying to interoperate with C, but will probably not surface unless you use LTO: https://bugs.r-project.org/show_bug.cgi?id=18430 Unfortunately, there's no standard DOUBLE COMPLEX. -- Best regards, Ivan [*] https://stevelionel.com/drfortran/2017/03/27/doctor-fortran-in-it-takes-all-kinds/ ______________________________________________ R-package-devel@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/r-package-devel
