--- Comment #34 from Thomas Henlich <thenlich at gcc dot gnu.org> --- Created attachment 47976 --> https://gcc.gnu.org/bugzilla/attachment.cgi?id=47976&action=edit Patch to fix issue with wrong exponent width for w=0 I appear to have found a fix for one of the remaining issues. This fixes "(D0.3)" -> got "0.314D-2", expected "0.314D-02" "(E0.10)" -> got "0.3139999928E-2", expected "0.3139999928E-02" More issues remain.
