Which strongly suggests that the cause is one of the many possible binary modules (Math::BigInt::BitVect, Math::BigInt::Pari and Math::BigInt::GMP.) that can sit behind use bignum doesn't properly handle log. If you could dump your %INC, maybe we could track down which one(s). Examine what is said, not who speaks -- Silence betokens consent -- Love the truth but pardon error.

log(10) works fine on my 5.8.5 rhel linux 4 box... (produces... "2.303585092994045684017991454684364207601") I also get 8.5 from the original question.	[reply]
