Minor quibble over the patch. I notice that integer division by abs_b occurs.

Belt and braces, but is zero a legal value for abs_b ? 

If so, it might be worth putting in some code to avoid divide by zero.

If not, it might be worth putting in some code to show the future
readers of the code that integer division by zero doesn't happen.
