4 Since Cython mixes C and Python semantics, some things may be a bit
5 surprising or unintuitive. Work always goes on to make Cython more natural
6 for Python users, so this list may change in the future.
8 - ``10**-2 == 0``, instead of ``0.01`` like in Python.
9 - Given two typed ``int`` variables ``a`` and ``b``, ``a % b`` has the
10 same sign as the second argument (following Python semantics) rather then
11 having the same sign as the first (as in C). The C behavior can be
12 obtained, at some speed gain, by enabling the division directive.
13 (Versions prior to Cython 0.12. always followed C semantics.)
14 - Care is needed with unsigned types. ``cdef unsigned n = 10;
15 print(range(-n, n))`` will print an empty list, since ``-n`` wraps
16 around to a large positive integer prior to being passed to the
18 - Python's ``float`` type actually wraps C ``double`` values, and
19 Python's ``int`` type wraps C ``long`` values.
