The varible precision root method I implemented has proven bounds , so cannot
ever be in error , I assume this is your objection , if not , what is it ?
Well, we're clearly in misunderstanding.
No, I don't object to code that is correct. As a matter of fact,
I much prefer correct code to incorrect code. It is a very
reasonable misunderstanding that you thought I liked incorrect
My point was that replacing mpz_root isn't the right change since
the real root extraction is performed at the mpn level. In the
development sources, there are several call sites for
