Hi,
I found the following bug in cygwin 1.7.8 on Windows XP:
Fortran I/O rounding truncates the result after a certain number of
digits. The following program:
===
write(*, '(f35.32)') 0.14285714285714285d0
end
===
gives this output:
0.14285714285714284921269000000000
The expected output is:
0.14285714285714284921269268124888
I don't think this has anything to do with cygin. On our linux system I get
With Intel ifort:
0.14285714285714284921269268124888
With gfortran 4.1.2s544
0.14285714285714284921269270000000
I agree. It's a GCC problem. I get the same results on Cygwin & Linux:
compiling with g77 gives correct output
compiling with gfortran does not.
