Ciao,
From
https://ci.debian.net/data/autopkgtest/testing/arm64/libm/libmath-gmp-perl/4229384/log.gz
I read the following:
# Failed test 'Test worked: $x =
Math::GMP->new("3878888047");Math::GMP::probab_prime($x,25);'
# at t/01_gmppm.t line 192.
# got: '2'
# expected: '1'
From the manual of GMP
https://gmplib.org/manual/Number-Theoretic-Functions.html I read the
following:
Function: int mpz_probab_prime_p (const mpz_t n, int reps)
Determine whether n is prime. Return 2 if n is definitely prime,
return 1 if n is probably prime (without being certain), or return 0 if
n is definitely non-prime.
So, if the new release of the library is able to answer that the number
3878888047 is prime, and not only "probably" prime... This should not be
marked as a regression...
Ĝis,
m
