[Axiom-developer] Bug in complexForm : complexForm(log(%i) - log(-%i)) -> 0

[Vladimir Bondarenko]

Hi *,

>From my teen years I got accustomed to see a simple
thing a certain way, but now I am amazed.

It would be great that an AXIOM connoisseur commented
the stuff, me, the outsider consider to be a sure bug.

Please confirm it or tell me why I am wrong here.


AXIOM Version of Wednesday December 15, 2004 at 00:50:38

AXIOM ->         complexForm(log(%i) - log(-%i))

                 0

COMPARE:

Derive 6.1>      LOG(#i) - LOG(-#i)
Maple 9.5.2>     ln(I) - ln(-I);
MuPAD 3.1>       ln(I) - ln(-I);
Mathematica 5.1> Log[I] - Log[-I]
Maxima 5.9.1>    RECTFORM(LOG(%I) - LOG(-%I));

                 #i*pi
                 I*Pi
                 I*PI
                 I*Pi
                 %I %PI

Much thanks for your comments in advance.


Best wishes,
