kargl at gcc dot gnu.org changed: What |Removed |Added ---------------------------------------------------------------------------- CC| |kargl at gcc dot gnu.org --- Comment #1 from kargl at gcc dot gnu.org --- (In reply to Bill Long from comment #0) > We have a customer who complained that the Fortran 2018 feature for > allowing w=0 in E-like format descriptors is not working with > gfortran version 9.2. I pointed them to the table at > https://gcc.gnu.org/wiki/Fortran2018Status and that the entry for > "d0.d, e0.d, es0.d, en0.d, g0.d and ew.d e0 edit descriptors" was > marked "No" They pointed out that the other two compilers they > commonly use (Cray and Intel) both support this feature. So, I'm > submitting their "bug", but changing it to a RFE. With the hope that > their input might help influence the priority given for this feature. > > Example test program: > > > > program test > real(8) :: r > r = atan(1.0) > r = r * 65536 > write (*,'(e0.6)') r > end program test You need to update to top-of-tree. It will be available when 10.1 is released.
