[Octave-bug-tracker] [bug #42071] complex trig functions differ from Matlab

[Mike Miller]

Update of bug #42071 (project octave):

                  Status:                    None => Need Info

Follow-up Comment #1:

Actually, I had someone check this in Matlab, and it looks to me like this is
just Matlab's default output formatting making you see something that's not
there :)

In Matlab:


>> real(exp(i*pi))
ans =
    -1
>> imag(exp(i*pi))
ans =
  1.2246e-016
>> imag(exp(i*20*pi))
ans =
 -2.4493e-015


These look the same as Octave to me, so I'm not sure there's a bug here. The
answers are what the underlying C math library calls return. Or am I missing
something?
