Details:

a = [2.5 + 3.200001i 5.3 + 4.4i];
dlmwrite('test.cvs',a,'precision',9)

gives file 
2.5g3.2gi,5.3g4.4gi


If I change line 124 in
/usr/share/octave/packages/io-1.0.9/dlmwrite.m
from
precision = sprintf ("%.%gg", precision);
to
precision = sprintf ("%%.%gg", precision);

then I get expected result
2.5+3.200001i,5.3+4.4i
