Duh ... Got confused with modulos (again).

def intdiv(a, b):
     return (a - (a % (-abs(b) if a < 0 else abs(b)))) / b

You should use // here to get an exact integer result.


You're totally right, thanks! It isn't an issue for Python 2.x's 
"classic division", but it becomes one with Python 3's "True division", 
and '//' allows to play it safe all along.
