Using a power-of-two base, you also save time, because conversion to/from
the internal representation is easier. This is one more reason for using
mpz_inp_raw and mpz_out_raw instead of the _str variants.

You can also use mpz_import and mpz_export if you want to cook your own
format: http://gmplib.org/manual/Integer-Import-and-Export.html .
