That's great, Alex, I also spent a lot of yesterday looking at the
same code. I look forward to seeing your patch and will test it on
both 32 and 64 bit machines.

Hi John,
I am about to put up a patch at #4064 (I'm adding a couple more doctests). It
is not perfect (it does not have proper doctests for 64 bit machines since I
don't have access to one), but I hope we can make it work soon.
Basically, I spent two days reading the libs/pari code and despairi

The more I look into this the more of a total mess it seems:
sage: pari(1.2345).precision() , pari('1.2345').precision()
(3, 4)
sage: pari(1.2345).python() , pari('1.2345').python()
(1.23443, 1.23450)
sage: pari(1.2345).python().prec() , pari('1.2345').

The pari library always and only measures precision in
number-of-codewords, and the prec parameter in pari library functions
always denotes this.
For the gp interface (to pari) decimal precisions are used, as they
are supposed to make more sense to huma
