+cnum()
+******
+
+Purpose
+=======
+
+cnum(expr)
+
+Converts expr to a number (integer).
+
+.. note::
+
+   If the expression does not contain a numerical value, the following
+   rule applies: the best match as the number is returned. For example
+   "1x234" will return the number 1 and "Test123" will return 0. Zero is
+   always returned if the there is no number at the start of the string.
+   This also is the case for empty strings.
+
+
+Example
+=======
+
+
+
+.. code-block:: none
+
+   cnum(3+2);
+
+produces
+
+.. code-block:: none
+
+   5
