Caveats
=======

Since Cython mixes C and Python semantics, some things may be a bit
surprising or unintuitive. Work always goes on to make Cython more natural
for Python users, so this list may change in the future.

 - ``10**-2 == 0``, instead of ``0.01`` like in Python.
 - Given two typed ``int`` variables ``a`` and ``b``, ``a % b`` has the
   same sign as the first argument (following C semantics) rather then
   having the same sign as the second (as in Python).  This will change
   in Cython 0.12.
 - Care is needed with unsigned types. ``cdef unsigned n = 10;
   print(range(-n, n))`` will print an empty list, since ``-n`` wraps
   around to a large positive integer prior to being passed to the
   ``range`` function.
 - Python's ``float`` type actually wraps C ``double`` values, and 
   Python's ``int`` type wraps C ``long`` values.
