==========================
Calculating values (+calc)
==========================

Sometimes a data type is set to ``someType +calc``. The ``+calc`` indicates
that the value is calculated with ``+-/\*`` operators. *Be aware that the
operators have no "weight".* The calculation is done from left to
right instead of order of operations (multiplication and division before addition and subtraction).
