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.
