Numeric expressions

In a composed string, if the field can contain a numeric field-value then you may use an arithmetic expression in place of a field-name. These operators may be used:

+ to add,

- to subtract,

* to multiply,

/ to divide (rounding towards zero),

\ to provide the remainder after division (the mod function)

and use round brackets () to contain intermediate calculations.



to check whether the current page number supplied by a field named pagenum is odd (when remainder is 1) or even (remainder is 0).


where field1, field2 and field3 all supply numeric values.
