(write_b): pass data length as extra parameter in calls to write_boz. (write_o): pass data length as extra parameter in calls to write_boz. (write_z): pass data length as extra parameter in calls to write_boz. (size_from_kind): also set size is default width is set. * io/write_float.def (build_float_string): new paramter inserted before result parameter. If default width use values passed instead of the values in fnode. (FORMAT_FLOAT): macro modified to check for default width and calls to build_float_string to pass in default width. (get_float_string): set width and precision to defaults when needed. From-SVN: r271511 |
