[Octave-bug-tracker] [bug #52627] Failing BIST tests on Mac OS X

[Rik]

Follow-up Comment #7, bug #52627 (project octave):

@Mike: Since you're quite familiar with the tests, do you know quickly why
this one in complex.tst is failing?


>>>>> processing complex.tst
***** test
 x = [complex(-1,0), complex(-1,-0), i, -i, 1];
 xs = sort (x);
 xf = single (x);
 xfs = sort (xf);
 assert (issorted (xs));
 assert (issorted (xfs));
 assert (double (xfs), xs);
!!!!! test failed
ASSERT errors for:  assert (double (xfs),xs)

  Location  |  Observed  |  Expected  |  Reason
    (1)         -1-0i        -0-1i       Abs err 1.4142 exceeds tol 0 by 1
    (2)         -0-1i         1+0i       Abs err 1.4142 exceeds tol 0 by 1
    (3)          1+0i         0+1i       Abs err 1.4142 exceeds tol 0 by 1
    (4)          0+1i        -1+0i       Abs err 1.4142 exceeds tol 0 by 1


It's obvious that the results aren't sorted according to the special sequence
that Octave uses of magnitude followed by phase angle, but we ship our own
sort routine as far as I know.
