Derive 6.1> LOG(#i) - LOG(-#i) gives #i*pi
Maple 9.5.2> ln(I) - ln(-I); gives I*Pi
MuPAD 3.1> ln(I) - ln(-I); gives I*PI
Mathematica 5.1> Log[I] - Log[-I] gives I*Pi
Maxima 5.9.1> RECTFORM(LOG(%I) - LOG(-%I)); gives %I %PI
However::
AXIOM -> complexForm(log(%i) - log(-%i)) gives 0
The problem is in the operation "argument":
