Details:



[X,Y] = meshgrid(0:6,0:6);
U = 0.25*X;
V = 0.5*Y;

quiver(X,Y,U,V,0)
figure, quiver(X,Y,int16(U),int16(V),0)

First one gives the expected plot. Second one produces a plot but every line
segment is connected to the origin. I'm aware the second plot isn't supposed
to be identical to the first one but this behavior seems like a bug.
