Arithmetic Formula
The arithmetic formula enables you to write simples formulas, such as
A + 1.2*B - C*D + 3.14. The formula can include four operands and a
set of operators or predefined functions. The supported operators are:
+,-,*,/,%,|,^,&,<<,>>,||,&&,==,!=,<,<=,>,>=. The operators are
described in Table 22 on page 164.
NOTE
The Unit string field entry will be used later in the AWS Client
software to display the unit of the sensor.

% Calculates the integer remainder r of oper1/oper2 such
that oper1 = i * oper2 + r, where i is integer and r has
same sign as oper1, and the absolute value of r is less
than the absolute value of oper2 .
