-- **Transparent calculations with uncertainties**: **no or little
-  modification of existing code** is needed.  Similarly, the Python_ (or
-  IPython_) shell can be used as **a powerful calculator** that
-  handles quantities with uncertainties (``print`` statements are
-  optional, which is convenient).

+  no modification of existing code is needed to convert calculations of floats

 - **Correlations** between expressions are correctly taken into
-  account.  Thus, ``x-x`` is exactly zero, for instance (most
-  implementations found on the web yield a non-zero uncertainty for
-  ``x-x``, which is incorrect).
