Follow-up Comment #3, bug #41855 (project octave):
One way to look at Octave is that it is just a pretty front-end on a lot of
very good numerical libraries. Some of the time this is obvious, Octave
doesn't implement it's own linear algebra solvers but relies on BLAS and
LAPACK. For some of the other basic math and trig functions, like sin, cos,
log2, we call the C libary routines. In this case the GNU libc log2 function
returns Inf + log2 (i) for log2 (Inf i). Since Octave is a GNU program we
choose the GNU C library as the canonical reference. Apple seems to have
chose a different value for this, admittedly strange, corner case.
