--- Comment #21 from Jerry DeLisle <jvdelisle at gcc dot gnu.org> --- (In reply to john.harper from comment #20) > With the first test case all the EN outputs were 666. but the Fortran 2018 > standard 13.7.2.3.4 paragraph 2 requires that EN0.0 produce 666.E+0 but > Table 13.2 first ENw.d line appears to require either 666.E+00 or 666.+000 > unless my copy of F2018 is out of date. (I note that the F2023 standard > removed the ambiguity by including "with w > 0" in the offending line of > Table 13.2.) However F2018 is unambiguous and agrees with F2023 on > EN0.0E0, requiring 666.E+0 > > With the second test case, which used 66600, I think all Jerry's outputs > are correct. I did not touch the code that writes the Exponent parts yet. So will have a look.
