[Octave-bug-tracker] [bug #48364] __run-test_suite_ FAIL for axis.m (tolerance)

[Philip Nienhuis]

Follow-up Comment #6, bug #48364 (project octave):

Just FTR I tried "test axis"before and after calling a Java function:

>> printf ("fpucw = 0x%04x\n", fpucw ());
fpucw = 0x027f
>> test axis
***** test
 hf = figure ("visible", "off");
 unwind_protect
   a = logspace (-5, 1, 10);
   loglog (a, -a);
   axis tight;
   assert (axis (), [1e-5, 10, -10, -1e-5]);
 unwind_protect_cleanup
   close (hf);
 end_unwind_protect
!!!!! test failed
ASSERT errors for:  assert (axis (),[1e-5, 10, -10, -1e-5])

fpucw = 0x037f

so am I right to surmise that the FPU control word seems to make little
difference?
