Hm, yes, I see that someone might. The two > operations, div and rem, need to be defined together. ----------------------------- 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. -- http://mail.python.org/mailman/listinfo/python-list
