Sorry, I accidentally hit sent. Here is the code and output
again:
? \p
20000
? bnf = bnfinit(x^2 + 199, flag=1);
? bnfisprincipal(bnf, bnf.gen[1] ^ 9)
*** bnfisprincipal: Warning: precision too low for generators,
not given.
%10 = [[1]~, []~]
I can reproduce this on the browser version
too. I am not sure what is happening or how to fix it. Should I
raise the precision even higher? Is this intended?
Best regards,
Gareth

Hi all.
I am trying to use `bnfisprincipal`, but it is somehow failing
even for very small inputs. Here is an example:
default(realprecision, 2000);
bnf = bnfinit(x^2 + 199, flag=1)bnfisprincipal(bnf, bnf.gen[1] ^
9)
*** bnfisprincipal: Warning: precision too low for generators,
