No, it's not. Precision and signedness have nothing to do with each
other. The main (only, really, when it comes down to it) difference
between a signed and an unsigned integer is that an unsigned integer is
defined never to have a value less than 0. There are very valid reasons
to enforce such a restriction, even when you want no upper limit (the
term infinite precision is not really appropriate for integers).
