But what did you use to write the numbers to a file?
For me under Mathematica 5.2, after generating some data,
inp = Table[Random[], {5}];
fin = inp * 10^# & /@ Range[-12, 12, 2];
The command
Export["test.dat", fin];
works just fine. As can be seen from online help on Export[] and
NumberForm[], there are more options available if you need a particular
alignment or to lose scientific notation entirely.
