[Octave-bug-tracker] [bug #50493] datetick crashes on certain date ranges

[Markus Mützel]

Follow-up Comment #4, bug #50493 (project octave):

Here the output in Matlab R2016a:

>> format compact
>> datestr(datenum([2017 1.5 1]))
ans =
01-Jan-2017
>> datestr(datenum([2017 1.8 1]))
ans =
01-Jan-2017
>> datestr(datenum([2017.6 1 1]))
ans =
08-Aug-2017
>> datestr(datenum([2017 1 1.8]))
ans =
01-Jan-2017 19:12:00
>> datestr(datenum([2017 1 1; 2017 1.5 1]))
ans =
01-Jan-2017
01-Jan-2017
>> datestr(datenum([2017 1 1; 2017.6 1 1]))
ans =
01-Jan-2017
08-Aug-2017
>> datestr(datenum([2017 1 1; 2017.7 1 1]))
ans =
01-Jan-2017 00:00:00
13-Sep-2017 12:00:00
>> datestr(datenum([2017 1 1; 2017 1 1.8]))
ans =
01-Jan-2017 00:00:00
01-Jan-2017 19:12:00


So the month seems to be always rounded down. Year and day on the other hand
float.

It might be worth to double check in a more recent version of Matlab whether
that rather inconsistent behavior has changed.
