[Octave-bug-tracker] [bug #65291] [octave forge] (mapping) degrees2dms produces incorrect results

[anonymous]

Follow-up Comment #4, bug#65291 (group octave):

With the proposed fix from comment #2, degrees2dms(2 - eps()) returns [1, 60,
59.9999999999990905052982270717620849609375] for me, which is off by 1 minute
or so.

If a well-defined specification for this function can be developed, it might
be feasible for proposed implementations to be exhaustively tested on inputs
of class single.

Some of the current test cases seem strange.  For instance, the exact result
for degrees2dms(10 + 0.5 / 60) would be [10, 0,
29.9999999999982946974341757595539093017578125] which is exactly
representable, but a test requires it to return exactly [10, 0, 30].
