I can get a modular reciprocal with Pari easily enough, eg:

  use Math::Pari qw/ PARI Mod /;
  my($n, $p) = map PARI($_), (3, 17);
  my $recip = PARI(1) / Mod($n, $p);
  print "1 / $n == $recip\n";

The result "Mod(6,17)" is a modular value, representing the equivalence class of integers equivalent to 6 (mod 17), and that's great.

However I now want to get the "6" out of there as an integer for further work, i.e. to get the "common residue" of that modular number. I haven't found anything in the Math::Pari or Pari/GP docs that tells how to do that, and everything I've tried gives an error:

  $int = int($recip);
PARI:   ***   incorrect type in comparison. at -e line 1.

  $int = pari2num($recip);
PARI:   ***   forbidden assignment t_INTMOD --> t_REAL. at -e line 1.

  $int = pari2iv($recip);
PARI:   ***   incorrect type in gtolong. at -e line 1.

I could pull the value out with a regexp, but that would be silly. Surely there is a simple, efficient way to do this?
