Details:

In MATLAB,


>> mod(11,-1)

ans =

     0

>> mod(12,-2)

ans =

     0

>> mod(15,-3)

ans =

     0

>> 


In Octave,


>> mod(13,-1)
ans = -0
>> mod(12,-3)
ans = -0
>> mod(15,-3)
ans = -0


So, for any integer n,x mod(nx,-x) giving -0.
What's the point of producing -0 when 0 and -0 is
same?
