Despite what the documentation says, the modulo operator does not return 
a remainder! Notice:
 >>> [x % 3 for x in range(-5,5)]
[1, 2, 0, 1, 2, 0, 1, 2, 0, 1]
For negative values of the left argument the result is NOT the 
remainder. The literature seems very confused about this, using 
"remainder" when it is NOT the case. What's worse, in some languages the 
mod operator DOES return the remainder.
