Gustavo,
I have no idea why you get 0. for a small number. It would help if you had a
simple example.
This gives the full numbers:
x = 6.54*^-3;
Table[x^(-10i), {i, -3, 3}]
To obtain scientific notation just use ScientificForm
x
0.00654
ScientificForm[x]
6.54 x 10^-3
You might also want to investigate NumberForm and EngineeringForm.
