-----------------------------
Haskell defines a quot-rem pair and a div-mod pair as follows:
(from http://www.haskell.org/onlinereport/basic.html)

(x `quot` y)*y + (x `rem` y) == x
(x `div`  y)*y + (x `mod` y) == x

`quot` is integer division truncated toward zero, while the result of
`div` is truncated toward negative infinity.
