Ok. Is there a way to predict the expected offset? I need to test if
the sums across the columns of a matrix are zero, or at least within
the bounds expected from the IEEE arithmetic.

I expected the below code to yield only zeros, but it does not:
That's just the way IEEE arithmetic works. When subtracting two
numbers that are very close, you may not get zero, just machine
epsilon. Try this, for fun: 0.3 - 0.2 - 0.1
