The attached patch attempts to fix the handling of the EN0.0E0 and
ES0.0E0 formatting by correctly calculating the number of digits needed
for the exponents and building those exponents into the float string.
while your patch addresses ENw.dE0 and ESw.dE0 formatting,
it does not fix Ew.dE0, which can be seen with the following test:
write(buffer,"(E0.3E0)") .6660_4
print *, buffer
write(buffer,"(E0.3)") .6660_4
print *, buffer
I get even with your patch:
0.666
0.666
but would have expected:
0.666E+0 ! F2018 & F2023, table 13.1
0.666E+0 ! F2023, table 13.1
The latter one is a bit ambiguous in F2018, but certainly gfortran's
current output in wrong.
Can you please check, and if you can fix that too, it would be great.
And if we do not want to be dependent on the standard version at
runtime, I'd rather go for F2023.
Certainly will look. This is why we need others checking. Corner cases
abound.
Cheers,
Jerry
