Follow-up Comment #20, bug #54342 (project octave):
Matlab and Octave seem to use a different rounding strategy with non integer
positive seeds: Octave using round() (as a consequence of casting to uint32?)
and Matlab using floor().
octave:1> rand('state',42)
octave:2> rand
ans = 0.6394
octave:3> rand('state',42.4)
octave:4> rand
ans = 0.6394
octave:5> rand('state',42.6)
octave:6> rand
ans = 0.038552
octave:7> rand('state',43)
octave:8> rand
ans = 0.038552
>> rand('state',42)
>> rand
ans =
0.1591
>> rand('state',42.4)
>> rand
ans =
0.1591
>> rand('state',42.6)
>> rand
ans =
0.1591
>> rand('state',43)
>> rand
ans =
0.3448
