It's what c does, c integers are modulo 2**(whatever). You could write a
special purpose ufunc for scaling arrays if you really need that option.
There was a simple example here using cython a while back <looks>, OK, here
it is on the cython wiki
So you might want to ask on the cython list since the example might be a
touch on the sketchy side...
