gp: algdep(sqrt(47/41),2) *** precision too low in mpent 

pari-dev,

? \v
          GP/PARI CALCULATOR Version 2.2.5 (development CHANGES-1.541)
                 UltraSparc (MicroSparc kernel) 32-bit version
              (readline v2.2 enabled, extended help not available)
? algdep(sqrt(47/41),2)
%1 = 41*x^2 - 47
? default(realprecision,29)
   realprecision = 38 significant digits (29 digits displayed)
? algdep(sqrt(47/41),2)
  ***   precision too low in mpent (precision loss in trucation).

This behavior is very puzzling and it would be nice to know how to
get around it if it can't be fixed. Shalom, Michael
